Description

本発明は、表裏の印刷層を備える情報表示パネル用積層シートに関し、特に遮光層および反射層を備えた情報表示パネル用積層シート、及び情報表示パネル、及び情報表示機器に関する。   The present invention relates to a laminated sheet for information display panels provided with front and back printed layers, and more particularly to a laminated sheet for information display panels comprising a light shielding layer and a reflective layer, an information display panel, and an information display device.

従来の情報表示パネルとして、透明基板の背面の文字・絵柄に対応する部分に開口部を含む有彩色の遮光反射層と白色の透過性反射層が順に積層され、表面には白色層と暗色層が順に積層され、文字・絵柄に対応する部分が開口部となっている構成を有するものがある。   As a conventional information display panel, a chromatic light-shielding reflective layer including an opening and a white transmissive reflective layer are sequentially laminated on a portion corresponding to characters / pictures on the back of a transparent substrate, and a white layer and a dark color layer are formed on the surface. Are sequentially stacked, and there is a structure in which a portion corresponding to a character / picture is an opening.

上記の情報表示パネルの構成を用いることで、ランプ非点灯時は、外光により、文字・絵柄部分が有彩色で囲まれた白色で視認され、文字・絵柄の周囲は暗色で視認される。また、ランプ点灯時は白色の透過反射層を透過し、有彩色の遮光反射層の開口部を抜けた白色の光が視認されるとともに、裏面から入射し、表面の白色層で反射した光が裏面の有彩色の遮光反射層で再度反射されて表面の開口部から抜けて有彩色の間接光状に視認される（特許文献１）。   By using the configuration of the information display panel described above, when the lamp is not lit, the light / character portion is visually recognized as white surrounded by a chromatic color, and the surroundings of the character / image are visually recognized as dark. In addition, when the lamp is lit, white light is transmitted through the white transmissive reflective layer, and the white light passing through the opening of the chromatic light-shielding reflective layer is visually recognized. The light is reflected again by the chromatic light-shielding / reflective layer on the back surface, passes through the opening on the front surface, and is visually recognized as chromatic indirect light (Patent Document 1).

実開平４−１２０９９０号4-120990

しかしながら、従来の技術ではランプ点灯時に有彩の間接光と白色の直接光で文字・絵柄の立体感を表現するものの、ランプ非点灯に外光により観察する場合と色は変わらず、ランプ点灯、非点灯で色変化をつけて表現することができなかった。
本発明は光源の点灯により、文字・絵柄等の外周部から漏れる間接光を観察者が視認することで文字・絵柄等に立体感を生じさせるとともに、光源の非点灯時との色変化をつけて文字・絵柄を美しく表現することを課題とする。 However, although the conventional technology expresses the three-dimensional effect of characters and pictures with chromatic indirect light and white direct light when the lamp is lit, the color remains the same as when observing with external light when the lamp is not lit, It was not illuminated and could not be expressed with color changes.
According to the present invention, when the light source is turned on, the viewer visually recognizes indirect light leaking from the outer peripheral portion of the character / pattern, etc., thereby creating a three-dimensional effect on the character / picture, etc., and adding a color change when the light source is not lit. The challenge is to express characters and designs beautifully.

本発明は光源の射出光が反射層で拡散反射され、文字・絵柄等の外周部である第１の領域から間接光として観察者に視認されるため、文字・絵柄等に立体感を生じさせる効果がある。また、光源射出光が光透過性着色層を透過して、間接光として視認されるため、光源の点灯時と非点灯時とで色の変化をつけて文字・絵柄を美しく表現することができる効果がある。   In the present invention, the light emitted from the light source is diffusely reflected by the reflective layer, and is visually recognized by the observer as indirect light from the first region, which is the outer periphery of the character / picture, etc. effective.

図１において、観察者７は光透過性の支持体８の一方の面側から目視し、光源６は支持体８の他方の面側に設置される。 Exemplary embodiments of an information display panel according to the present invention will be described below in detail with reference to the drawings.
FIG. 1 is a cross-sectional view of a laminated sheet 4 for an information display panel 5 according to a first embodiment of the present invention, taken along a plane perpendicular to the sheet extending direction. (A) shows each layer separated for easy understanding of the order of lamination, and (B) shows a state in which the layers are actually laminated.
As shown in FIG. 1, the laminated sheet 4 includes a first region 1, a second region 2, and a third region that are adjacent to the first region 1 and separated from each other, as viewed from the sheet thickness direction. Divided into three.
A design shape such as a pattern is configured by the shapes of the first to third regions on the extending surface of the laminated sheet 4.
Note that other regions apart from the second and third regions may be further provided. In that case, the first region is disposed adjacent to the further provided region.
In FIG. 1, an observer 7 views from one surface side of a light-transmissive support 8, and the light source 6 is installed on the other surface side of the support 8.

支持体８の観察者６側の面のうち第１の領域１に、第１の拡散層３１、第４の加飾層１７が順に積層されている。
また、支持体８の観察者６側の面のうち第２の領域２に、第２の拡散層３２、第２の反射層１１、第２の加飾層１２が順に積層されている。
さらに、支持体８の観察者６側の面のうち第３の領域３に、第２の拡散層３２、第３の反射層１３、第２の遮光層１４、第２の加飾層１５、透明加飾層１６が順に積層されている。
支持体８の光源６側の面のうち第１の領域１に、第１の反射層２１、第１の遮光層２３、光透過性着色層２４が順に積層されている。
また、支持体８の光源６側の面のうち第２の領域２に、光透過性着色層２４が設けられている。
さらに、支持体８の光源６側の面のうち第３の領域３に、第４の反射層２２、第１の遮光層２３、光透過性着色層２４が順に積層されている。 A first diffusion layer 31 and a fourth decorative layer 17 are sequentially stacked in the first region 1 on the surface of the support 8 on the viewer 6 side.
In addition, the second diffusion layer 32, the second reflection layer 11, and the second decoration layer 12 are sequentially laminated in the second region 2 on the surface of the support 8 on the viewer 6 side.
Further, the second diffusion layer 32, the third reflective layer 13, the second light shielding layer 14, the second decorative layer 15, in the third region 3 of the surface of the support 8 on the viewer 6 side, The transparent decoration layer 16 is laminated | stacked in order.
A first reflective layer 21, a first light-shielding layer 23, and a light-transmitting colored layer 24 are sequentially laminated in the first region 1 on the surface of the support 8 on the light source 6 side.
Further, a light transmissive colored layer 24 is provided in the second region 2 of the surface of the support 8 on the light source 6 side.
Further, a fourth reflective layer 22, a first light shielding layer 23, and a light-transmitting colored layer 24 are sequentially laminated on the third region 3 in the surface of the support 8 on the light source 6 side.

支持体８は、透明樹脂のみで構成するか、又は拡散性樹脂のみで構成するか、又は透明樹脂層と拡散性樹脂層との積層によって構成することができる。
ここで、支持体４のヘイズ値は１２％以上９２％以下であることが望ましい。
支持体４のヘイズ値が１２％未満の場合、支持体４に入射して拡散反射して第１の領域１に抜ける光が減少するために、間接光の輝度が低下するという弊害があるからである。 The support 8 can be composed of only a transparent resin, can be composed of only a diffusible resin, or can be composed of a laminate of a transparent resin layer and a diffusible resin layer.
Here, the haze value of the support 4 is desirably 12% or more and 92% or less.
When the haze value of the support 4 is less than 12%, the light that enters the support 4 and diffuses and reflects and passes through the first region 1 is reduced, which causes a disadvantage that the brightness of the indirect light is reduced. It is.

支持体８を透明樹脂のみで構成する場合、ポリカーボネート、ポリプロピレン、発泡ポリプロピレン、ポリエチレンテレフタレート、ポリスチレン、メタクリル・スチレン共重合体、アクリルニトリル・スチレン共重合体、ポリメタクリル酸メチルまたはアクリルを利用することができる。この時の支持体８の厚さは第２の反射層１１及び第３の反射層１３で拡散反射された光を多く第１の領域１に進ませるために０．１ｍｍ以上が好ましく、情報表示機器筐体内の空間的制約を受けないために５ｍｍ以下が好ましい。また、透明樹脂のみで構成すると支持体８における光量の損失を少なく出来るため、光源６の点灯時により明るく文字・絵柄を表示することができる。   When the support 8 is composed only of a transparent resin, polycarbonate, polypropylene, expanded polypropylene, polyethylene terephthalate, polystyrene, methacryl / styrene copolymer, acrylonitrile / styrene copolymer, polymethyl methacrylate or acrylic may be used. it can. The thickness of the support 8 at this time is preferably 0.1 mm or more so that a large amount of light diffusely reflected by the second reflective layer 11 and the third reflective layer 13 is advanced to the first region 1. It is preferably 5 mm or less so as not to be restricted by the space in the device casing. Further, since the loss of the light amount in the support 8 can be reduced if it is composed only of the transparent resin, it is possible to display characters and designs brighter when the light source 6 is turned on.

支持体８を拡散性樹脂のみで構成する場合、球形または無定形の形状であり有機又は無機からなる光拡散性微粒子を含んだポリカーボネート、ＰＳ、ＭＳ、アクリルのうち少なくともいずれかを含む有機系樹脂を利用することができる。この時の支持体８の厚さは第２の反射層１１及び第３の反射層１３で拡散反射された光を多く第１の領域１に進ませるために０．１ｍｍ以上が好ましく、情報表示機器筐体内の空間的制約を受けないために５ｍｍ以下が好ましい。また、拡散樹脂のみで構成することにより、光源６からの直接入射光の一部が拡散樹脂で拡散されて第２の反射層１１と第３の反射層１３及び第１の領域１に出るために間接光の光量を高められる。   When the support 8 is composed only of a diffusible resin, it is a spherical or amorphous shape, and an organic resin containing at least one of polycarbonate, PS, MS, and acryl containing organic or inorganic light diffusing fine particles. Can be used. The thickness of the support 8 at this time is preferably 0.1 mm or more so that a large amount of light diffusely reflected by the second reflective layer 11 and the third reflective layer 13 is advanced to the first region 1. It is preferably 5 mm or less so as not to be restricted by the space in the device casing. In addition, since only a part of the direct incident light from the light source 6 is diffused by the diffusion resin by being composed only of the diffusion resin, the second reflection layer 11, the third reflection layer 13, and the first region 1 are emitted. The amount of indirect light can be increased.

支持体８を透明樹脂層と拡散性樹脂層との積層構成にする場合、透明樹脂層にはポリカーボネート、ポリプロピレン、発泡ポリプロピレン、ポリエチレンテレフタレート、ポリスチレン、メタクリル・スチレン共重合体、アクリルニトリル・スチレン共重合体、ポリメタクリル酸メチルまたはアクリルを、拡散性樹脂層には球形または無定形の形状であり有機又は無機からなる光拡散性微粒子を含んだポリカーボネート、ポリスチレン、メタクリルスチレン共重合体、アクリルのうち少なくともいずれかを含む有機系樹脂を利用することができる。この時の支持体８の厚さは第２の反射層１１及び第３の反射層１３で拡散反射された光を多く第１の領域１に進ませるために０．１ｍｍ以上が好ましく、情報表示機器筐体内の空間的制約を受けないために５ｍｍ以下が好ましい。また、拡散樹脂層を含む構成であることにより、光源６からの直接入射光の一部が拡散樹脂層で拡散されて第２の反射層１１と第３の反射層１３及び第１の領域１の観察者の方向に出るために間接光の光量を高められる。
ここで、拡散性樹脂層はヘイズ値が１２％以上９２％以下の樹脂であることが望ましい。拡散性樹脂層のヘイズ値が１２％未満の場合、支持体に入射して拡散反射して、第１の領域１に抜ける光が減少するために、間接光の輝度が低下するという弊害があるからである。 When the support 8 has a laminated structure of a transparent resin layer and a diffusible resin layer, the transparent resin layer includes polycarbonate, polypropylene, expanded polypropylene, polyethylene terephthalate, polystyrene, methacryl / styrene copolymer, acrylonitrile / styrene copolymer. Polymer, polymethylmethacrylate or acrylic, and at least one of polycarbonate, polystyrene, methacrylstyrene copolymer, acrylic containing light diffusing fine particles made of organic or inorganic in a sphere or amorphous shape in the diffusible resin layer Any organic resin containing any of them can be used. The thickness of the support 8 at this time is preferably 0.1 mm or more so that a large amount of light diffusely reflected by the second reflective layer 11 and the third reflective layer 13 is advanced to the first region 1. It is preferably 5 mm or less so as not to be restricted by the space in the device casing. Further, since the structure includes the diffusion resin layer, a part of the direct incident light from the light source 6 is diffused by the diffusion resin layer, and the second reflection layer 11, the third reflection layer 13, and the first region 1 are diffused. The amount of indirect light can be increased in order to go in the direction of the observer.
Here, the diffusible resin layer is preferably a resin having a haze value of 12% or more and 92% or less. When the haze value of the diffusible resin layer is less than 12%, the light that enters the support and diffuses and reflects and passes through the first region 1 is reduced, so that the luminance of indirect light is lowered. Because.

次に支持体８の観察者６側の積層構造について詳細に説明する。
支持体８の観察者６側の面のうち第１の領域に第１の拡散層３１が配置される。
第１の拡散層３１はスクリーン印刷によって設けることができる。特にスクリーン印刷に限定することなく、凸版印刷、フレキソ印刷、オフセット印刷、グラビア印刷、インクジェット等を用いることができる。
第１の拡散層３１には透明インキを用いるのが望ましいが、光の拡散効果、透過効果があれば透明インキに限らない。厚みに制限は無いが、５μｍ〜３０μｍにすると拡散効果が出やすい。
また、第１の拡散層３１のヘイズ値は５％以上、全光線透過率は６０％以上であることが望ましい。この数値範囲は、第１の拡散層３１のヘイズ値が５％未満の場合、第１の拡散層３１への入射光を第２の領域２、第３の領域３へ拡散反射する効果が十分に得られず、第１の拡散層３１の全光線透過率が６０％未満の場合、第１の領域１に通り抜ける光が減少するために輝度が低下するという弊害があるからである。
第１の拡散層３１は光源６の非点灯時に第１の領域１を観察した際における支持体８表面での反射光による眩しさを低減させる効果がある。同時に光透過性があるため光源６の点灯時の第１の領域１における間接光の視認を妨げない。
第１の拡散層３１は必ず設けなければならないわけではなく、前述の支持体８表面での反射光の低減及びデザイン上の必要性がなければ設ける必要はない。 Next, the laminated structure on the viewer 6 side of the support 8 will be described in detail.
The first diffusion layer 31 is disposed in the first region of the surface of the support 8 on the viewer 6 side.
The first diffusion layer 31 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing.
Although it is desirable to use a transparent ink for the first diffusion layer 31, it is not limited to the transparent ink as long as it has a light diffusion effect and a light transmission effect. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, a diffusion effect will come out easily.
Further, it is desirable that the first diffusion layer 31 has a haze value of 5% or more and a total light transmittance of 60% or more. In this numerical range, when the haze value of the first diffusion layer 31 is less than 5%, the effect of diffusing and reflecting the incident light to the first diffusion layer 31 to the second region 3 and the third region 3 is sufficient. This is because if the total light transmittance of the first diffusion layer 31 is less than 60%, the light passing through the first region 1 is reduced, so that the luminance is lowered.
The first diffusion layer 31 has an effect of reducing glare due to reflected light on the surface of the support 8 when the first region 1 is observed when the light source 6 is not lit. At the same time, since the light is transmissive, the visual recognition of indirect light in the first region 1 when the light source 6 is turned on is not hindered.
The first diffusion layer 31 is not necessarily provided, and it is not necessary to provide the first diffusion layer 31 unless there is a need for reduction of reflected light on the surface of the support 8 and design.

第１の拡散層３１（第１の拡散層３１がない場合は支持体８）の観察者６側の面のうち第１の領域１の一部に第４の加飾層１７を設ける。
なお、図１（Ａ）において、積層の順序、種類をわかりやすくするため、加飾層１３を第１の加飾層と同じ段に表示しているが、実際は（Ｂ）のように拡散層３１の観察者６側の面に積層されている。
第４の加飾層１７はスクリーン印刷によって設けることができる。特にスクリーン印刷に限定することなく、凸版印刷、フレキソ印刷、オフセット印刷、グラビア印刷、インクジェット等を用いることができる。
第４の加飾層１７には黒色インキを用いるのが望ましいが、遮光効果があれば黒色インキに限らない。厚みに制限は無いが、５μｍ〜３０μｍにすると遮光効果が出やすい。
また、第４の加飾層１７の全光線透過率は２０％以下であることが望ましい。
第４の加飾層１７の全光線透過率が２０％より大きい場合に、第４の加飾層１７の透過光が視認され、第１の領域における第４の加飾層１７のない部分とのコントラストが低下し、第４の加飾層１７の視認性が低下するという弊害があるからである。
光源が点灯した際に第１の領域１には間接光が広がるが、第１の領域１の一部に第４の加飾層１７があるためにその部分は遮光され、絵柄として視認される。第４の加飾層１７はデザイン上必要があれば設けることができ、第４の加飾層１７が無くても情報表示パネル５における他の機能には影響がない。 A fourth decorative layer 17 is provided on a part of the first region 1 on the surface of the first diffusion layer 31 (the support 8 when there is no first diffusion layer 31) on the viewer 6 side.
In FIG. 1A, the decorative layer 13 is displayed on the same stage as the first decorative layer in order to make the order and type of the layers easy to understand, but in reality, the diffusion layer is as shown in FIG. 31 are stacked on the surface of the viewer 6 side.
The fourth decorative layer 17 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing.
Although it is desirable to use black ink for the 4th decoration layer 17, if there is a light-shielding effect, it will not be restricted to black ink. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, the light-shielding effect will come out easily.
In addition, the total light transmittance of the fourth decorative layer 17 is desirably 20% or less.
When the total light transmittance of the 4th decoration layer 17 is larger than 20%, the transmitted light of the 4th decoration layer 17 is visually recognized, and the part which does not have the 4th decoration layer 17 in a 1st area | region This is because there is an adverse effect that the contrast of the fourth decorative layer 17 decreases and the visibility of the fourth decorative layer 17 decreases.
When the light source is turned on, indirect light spreads in the first region 1, but since there is the fourth decorative layer 17 in a part of the first region 1, that portion is shielded and visually recognized as a pattern. . The fourth decorative layer 17 can be provided if necessary in terms of design, and even if the fourth decorative layer 17 is not provided, other functions in the information display panel 5 are not affected.

支持体８の観察者６側の面のうち第２の領域２及び第３の領域３に第２の拡散層３２が配置される。
第２の拡散層３２はスクリーン印刷によって設けることができる。特にスクリーン印刷に限定することなく、凸版印刷、フレキソ印刷、オフセット印刷、グラビア印刷、インクジェット等を用いることができる。
第２の拡散層３２には透明インキを用いるのが望ましいが、光の拡散効果、透過効果があれば透明インキに限らない。厚みに制限は無いが、５μｍ〜３０μｍにすると拡散効果が出やすい。
第２の拡散層３２のヘイズ値は５％以上、全光線透過率は６０％以上９８％以下であることが望ましい。この数値範囲は、第２の拡散層３２のヘイズ値が５％未満の場合、第２の拡散層３２への入射光を第１の領域１へ拡散反射する効果が十分に得られず、第２の拡散層３２の全光線透過率が６０％未満の場合、第２の反射層１１、第３の反射層１３に入射する光量が低下することにより、第１の領域１への反射光の輝度が低下して立体感が損なわれることを考慮したものである。
第２の拡散層３２は光源６の点灯時に支持体８から入射した光の一部を拡散して第１の領域１に出射することにより、第１の領域１における間接光の輝度をあげて第１の領域１と第２の領域２の境界及び第１の領域１と第３の領域３の境界における立体感を向上させる効果がある。
第２の拡散層３２は必ず設けなければならないわけではなく、第１の領域１における輝度の向上が必要な場合に設けることができる。 The second diffusion layer 32 is disposed in the second region 2 and the third region 3 on the surface of the support 8 on the viewer 6 side.
The second diffusion layer 32 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing.
Although it is desirable to use a transparent ink for the second diffusion layer 32, it is not limited to the transparent ink as long as it has a light diffusion effect and a light transmission effect. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, a diffusion effect will come out easily.
The haze value of the second diffusion layer 32 is preferably 5% or more, and the total light transmittance is preferably 60% or more and 98% or less. In this numerical range, when the haze value of the second diffusion layer 32 is less than 5%, the effect of diffusing and reflecting incident light to the second diffusion layer 32 to the first region 1 cannot be sufficiently obtained. When the total light transmittance of the second diffusing layer 32 is less than 60%, the amount of light incident on the second reflecting layer 11 and the third reflecting layer 13 is reduced, so that the reflected light to the first region 1 is reduced. This is because the three-dimensional effect is impaired due to a decrease in luminance.
The second diffusion layer 32 diffuses part of the light incident from the support 8 when the light source 6 is turned on and emits the light to the first region 1, thereby increasing the brightness of the indirect light in the first region 1. There is an effect of improving the stereoscopic effect at the boundary between the first region 1 and the second region 2 and at the boundary between the first region 1 and the third region 3.
The second diffusion layer 32 is not necessarily provided, and can be provided when the luminance in the first region 1 needs to be improved.

第２の拡散層３２（第２の拡散層３２がない場合は支持体８）の観察者６側の面のうち第２の領域２に第２の反射層１１が配置される。
第２の反射層１１は入射した光が所定の確率で拡散反射する効果を有するものである。
第２の反射層１１はスクリーン印刷によって設けることができる。特にスクリーン印刷に限定することなく、凸版印刷、フレキソ印刷、オフセット印刷、グラビア印刷、インクジェット等を用いることができる。
第２の反射層１１には白色インキを用いるのが望ましいが、光の反射効果、透過効果があれば白色インキに限らない。厚みに制限は無いが、５μｍ〜３０μｍにすると反射効果が出やすい。
また、第２の反射層１１における３８０〜７８０ｎｍの光線の反射率は６０％以上であり、第２の反射層１１の全光線透過率は５％以上４０％以下であることが望ましい。
第２の反射層１１の反射率が６０％未満であった場合、第２の反射層１１で反射される間接光の輝度が低下し、第１の領域１と第２の領域２の境界における立体感が損なわれるからである。また、第２の反射層１１の全光線透過率が５％未満であると、第１の加飾層１２に文字等意匠形状の開口部が設けられた場合にその部分の輝度が低く、文字等意匠形状が視認されないからである。一方、全光線透過率が４０％以上であると反射率が低下して、前述のように間接光の輝度低下による第１の領域と第２の領域の境界における立体感の低下が起こるためである。
光源６が点灯した際には第２の反射層１１で反射した光が第１の領域１で間接光として視認される。この時、第２の領域２の第２の反射層１１の幅が広い方が第１の領域１に向けて拡散反射される光が多いために輝度が高くなり、第１の領域１と第２の領域２の境界における立体感が高まる。また、デザイン上第２の領域２に文字等意匠形状を設ける場合、第２の反射層１１または第２の反射層１１の開口部を透過した光が後述する第１の加飾層１２の開口部を抜けることにより、観察者から直接光として文字等意匠形状が視認される。 The second reflective layer 11 is arranged in the second region 2 of the surface of the second diffusion layer 32 (the support 8 when there is no second diffusion layer 32) on the viewer 6 side.
The second reflective layer 11 has an effect that the incident light is diffusely reflected with a predetermined probability.
The second reflective layer 11 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing.
Although it is desirable to use white ink for the second reflective layer 11, it is not limited to white ink as long as it has a light reflection effect and transmission effect. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, a reflective effect will come out easily.
Further, it is desirable that the reflectance of light of 380 to 780 nm in the second reflective layer 11 is 60% or more, and the total light transmittance of the second reflective layer 11 is 5% or more and 40% or less.
When the reflectance of the second reflective layer 11 is less than 60%, the brightness of the indirect light reflected by the second reflective layer 11 is reduced, and the boundary between the first region 1 and the second region 2 is reduced. This is because the stereoscopic effect is impaired. Further, when the total light transmittance of the second reflective layer 11 is less than 5%, when the first decorative layer 12 is provided with an opening having a design shape such as a character, the luminance of the portion is low, and the character This is because the iso-design shape is not visually recognized. On the other hand, if the total light transmittance is 40% or more, the reflectance is lowered, and as described above, the stereoscopic effect at the boundary between the first region and the second region is lowered due to the luminance reduction of the indirect light. is there.
When the light source 6 is turned on, the light reflected by the second reflective layer 11 is visually recognized as indirect light in the first region 1. At this time, the larger the width of the second reflective layer 11 in the second region 2, the higher the luminance because there is more light diffusely reflected toward the first region 1, and the first region 1 and the first region 1 The stereoscopic effect at the boundary between the two regions 2 is increased. Moreover, when providing design shapes, such as a character, in the 2nd area | region 2 on design, the opening of the 1st decorating layer 12 which the light which permeate | transmitted the opening part of the 2nd reflective layer 11 or the 2nd reflective layer 11 mentions later. By passing through the part, the design shape such as letters is visually recognized as direct light from the observer.

第２の反射層１１の観察者７側の面に第１の加飾層１２が積層される。第１の加飾層１２はスクリーン印刷によって設けることができる。特にスクリーン印刷に限定することなく、凸版印刷、フレキソ印刷、オフセット印刷、グラビア印刷、インクジェット等を用いることができる。第１の加飾層６には黒色インキを用いるのが望ましいが、遮光効果があれば黒色インキに限らない。厚みに制限は無いが、５μｍ〜３０μｍにすると遮光効果が出やすい。
また、第１の加飾層１２の全光線透過率は、２０％以下の範囲で略一定であることが望ましい。
全光線透過率が２０％より大きい場合、第２の領域２における第２の反射層１１の透過光を遮光できず、第１の領域１と第２の領域２との間のコントラストが低下し、立体感が損なわれるという弊害があるからである。
第１の加飾層１２は第２の領域２における絵柄を表すとともに、第２の反射層１１を透過する光源６の光を遮光する。また、第２の領域２に文字等意匠形状が設けられる場合、第１の加飾層１２に文字等意匠形状の開口部が設けられ、第２の反射層１１を透過した光が第１の加飾層１２の開口部を抜けることにより、観察者から文字等意匠形状が直接光として視認される。 A first decorative layer 12 is laminated on the surface of the second reflective layer 11 on the viewer 7 side. The first decorative layer 12 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing. Although it is desirable to use black ink for the 1st decoration layer 6, if there is a light-shielding effect, it will not be restricted to black ink. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, the light-shielding effect will come out easily.
Moreover, it is desirable that the total light transmittance of the first decorative layer 12 is substantially constant within a range of 20% or less.
When the total light transmittance is larger than 20%, the transmitted light of the second reflective layer 11 in the second region 2 cannot be blocked, and the contrast between the first region 1 and the second region 2 is lowered. This is because the three-dimensional effect is impaired.
The first decorative layer 12 represents a pattern in the second region 2 and shields light from the light source 6 that passes through the second reflective layer 11. Further, when a design shape such as a character is provided in the second region 2, an opening of the design shape such as a character is provided in the first decorative layer 12, and the light transmitted through the second reflective layer 11 is the first By passing through the opening of the decorative layer 12, the design shape such as letters is visually recognized as direct light by an observer.

第２の拡散層３２（第２の拡散層３２がない場合は支持体８）の観察者６側の面のうち第３の領域３に開口部を有する第３の反射層１３が配置される。
第３の反射層１３は入射した光が所定の確率で拡散反射する効果を有するものである。
第３の反射層１３はスクリーン印刷によって設けることができる。特にスクリーン印刷に限定することなく、凸版印刷、フレキソ印刷、オフセット印刷、グラビア印刷、インクジェット等を用いることができる。
第３の反射層１３には白色インキを用いるのが望ましいが、光の反射効果があれば白色インキに限らない。厚みに制限は無いが、５μｍ〜３０μｍにすると反射効果が出やすい。
また、第３の反射層１３における３８０〜７８０ｎｍの光線の反射率は６０％以上であることが望ましい。
第３の反射層１３の反射率が６０％未満であった場合、第３の反射層１３で反射される間接光の輝度が低下し、第１の領域１と第２の領域２の境界における立体感が損なわれるからである。
光源６が点灯した際には第３の反射層１３で反射した光が、支持体８の光源側の面のうち第１の領域に設けられた第１の反射層２１及び第３の領域３に設けられた第４の反射層２２に入射する。このうち第１の領域１のものは間接光として視認され、第３の領域３のものは第３の反射層１３と第２の遮光層１４の開口部を抜けて第２の加飾層１５と透明加飾層１６を透過して観察者に視認される。
この時、第３の反射層１３の開口部を除いた面積が大きい方が第３の反射層１３で反射されて第１の領域で間接光として観察される光が多く、第１の領域１と第３の領域３の境界における立体感が高まる。 The third reflective layer 13 having an opening in the third region 3 is disposed on the surface of the second diffusion layer 32 (the support 8 when there is no second diffusion layer 32) on the viewer 6 side. .
The third reflective layer 13 has the effect of diffusely reflecting incident light with a predetermined probability.
The third reflective layer 13 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing.
Although it is desirable to use white ink for the third reflective layer 13, it is not limited to white ink as long as it has a light reflection effect. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, a reflective effect will come out easily.
Further, it is desirable that the reflectance of light of 380 to 780 nm in the third reflective layer 13 is 60% or more.
When the reflectance of the third reflective layer 13 is less than 60%, the luminance of the indirect light reflected by the third reflective layer 13 is reduced, and the boundary between the first region 1 and the second region 2 is reduced. This is because the stereoscopic effect is impaired.
When the light source 6 is turned on, the light reflected by the third reflective layer 13 is provided in the first region on the light source side surface of the support 8 and the third region 3. The light is incident on the fourth reflective layer 22 provided on the surface. Among these, those in the first region 1 are visually recognized as indirect light, and those in the third region 3 pass through the openings of the third reflective layer 13 and the second light shielding layer 14 and the second decorative layer 15. And is visible to the observer through the transparent decorative layer 16.
At this time, when the area of the third reflective layer 13 excluding the opening is larger, more light is reflected by the third reflective layer 13 and observed as indirect light in the first region. And the three-dimensional effect at the boundary of the third region 3 is increased.

第３の反射層１３の観察者７側の面に第２の遮光層１４が積層される。
第２の遮光層１４はスクリーン印刷によって設けることができる。特にスクリーン印刷に限定することなく、凸版印刷、フレキソ印刷、オフセット印刷、グラビア印刷、インクジェット等を用いることができる。
第２の遮光層１４には黒色インキを用いるのが望ましいが、遮光効果があれば黒色インキに限らない。厚みに制限は無いが、５μｍ〜３０μｍにすると遮光効果が出やすい。
第２の遮光層１４の全光線透過率は２０％以下であることが望ましい。第２の遮光層１４の全光線透過率が２０％より大きい場合、第３の反射層１３を透過した光が直接視認されてしまい、第２の遮光層１４の開口部を透過する光とのコントラストが低下して、第２の加飾層１５、透明加飾層１６を通してみえる絵柄を美しく表示できないためである。
光源６が点灯した際には第２の拡散層３２から第３の反射層１３へ進入した光が第３の反射層１３で概ね反射、吸収されるが、反射されなかった光が第２の遮光層１４に進入する。第２の遮光層１４はその光を遮光することで、第１の領域１の間接光と第３の領域３の境界部分のコントラストを高めて立体感を出し、また第３の反射層１３の開口部を抜けて第２の加飾層１５と透明加飾層１６を透過する光との輝度差を出すことで第３の領域の絵柄を表現できる。 A second light shielding layer 14 is laminated on the surface of the third reflective layer 13 on the viewer 7 side.
The second light shielding layer 14 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing.
Although it is desirable to use black ink for the 2nd light shielding layer 14, if it has a light-shielding effect, it will not be restricted to black ink. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, the light-shielding effect will come out easily.
The total light transmittance of the second light shielding layer 14 is desirably 20% or less. When the total light transmittance of the second light shielding layer 14 is larger than 20%, the light transmitted through the third reflective layer 13 is directly recognized, and the light transmitted through the opening of the second light shielding layer 14 This is because the contrast is lowered and the picture seen through the second decorative layer 15 and the transparent decorative layer 16 cannot be displayed beautifully.
When the light source 6 is turned on, the light that has entered the third reflective layer 13 from the second diffusion layer 32 is substantially reflected and absorbed by the third reflective layer 13, but the light that has not been reflected is second The light enters the light shielding layer 14. The second light-shielding layer 14 shields the light, thereby increasing the contrast of the boundary between the indirect light of the first region 1 and the third region 3 to give a stereoscopic effect. The pattern of the third region can be expressed by calculating the luminance difference between the light that passes through the opening and passes through the second decorative layer 15 and the transparent decorative layer 16.

第２の拡散層３２（第２の拡散層３２がない場合は支持体８）の観察者６側の面のうち第３の反射層１３の開口部に相当する面、及び第２の遮光層１４の観察者６側の面に積層された第２の加飾層１５が、第３の領域全域に亘って配置される。
第２の加飾層１５はスクリーン印刷によって設けることができる。特にスクリーン印刷に限定することなく、凸版印刷、フレキソ印刷、オフセット印刷、グラビア印刷、インクジェット等を用いることができる。
第２の加飾層１５には灰色インキを用いるのが望ましいが、半透過性であれば灰色インキに限らない。厚みに制限は無いが、５μｍ〜３０μｍにすると半透過性が出やすい。
また、第２の加飾層１５の全光線透過率は４％以上４０％以下であることが望ましい。
第２の加飾層１５の全光線透過率が４％未満の場合、第２の遮光層１４の開口部を抜ける光が視認できず、光源点灯時に第３の領域３の絵柄が視認できないという弊害があるからである。一方、第２の加飾層１５の全光線透過率が４０％より大きい場合、光源非点灯時に第２の遮光層１４の開口部１４を隠蔽することができず、光源の点灯時、非点灯時の第３の領域３の絵柄の違いを表現することができないという弊害があるからである。
第２の加飾層１５は光源６の非点灯時には第３の反射層１３及び第２の遮光層１４とその開口部を隠蔽し、観察者から第三の加飾層３は第２の加飾層１５及び透明加飾層１６だけで構成されているように視認される。一方、光源６の点灯時に第２の加飾層１５は第３の反射層１３及び第２の遮光層１４の開口部を抜ける光を透過させて透明加飾層１６に入射させることにより、非点灯時と別の美しい意匠性を表現することができる。 Of the surface on the viewer 6 side of the second diffusion layer 32 (the support 8 when there is no second diffusion layer 32), the surface corresponding to the opening of the third reflective layer 13, and the second light shielding layer The 14th decorating layer 15 laminated | stacked on the surface at the side of 14 observers 6 is arrange | positioned over the 3rd area | region whole region.
The second decorative layer 15 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing.
Although it is desirable to use a gray ink for the 2nd decoration layer 15, if it is translucent, it will not restrict to a gray ink. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, semi-permeable property will come out easily.
The total light transmittance of the second decorative layer 15 is preferably 4% or more and 40% or less.
When the total light transmittance of the second decorative layer 15 is less than 4%, the light passing through the opening of the second light shielding layer 14 cannot be visually recognized, and the design of the third region 3 cannot be visually recognized when the light source is turned on. This is because there are harmful effects. On the other hand, when the total light transmittance of the second decorative layer 15 is greater than 40%, the opening 14 of the second light shielding layer 14 cannot be concealed when the light source is not turned on, and is not turned on when the light source is turned on. This is because there is an adverse effect that the difference in the pattern of the third region 3 at the time cannot be expressed.
The second decorative layer 15 conceals the third reflective layer 13 and the second light-shielding layer 14 and the opening when the light source 6 is not lit. It is visually recognized as being composed only of the decorative layer 15 and the transparent decorative layer 16. On the other hand, when the light source 6 is turned on, the second decorative layer 15 transmits light that passes through the openings of the third reflective layer 13 and the second light shielding layer 14 and enters the transparent decorative layer 16 to thereby prevent non-reflection. It is possible to express a beautiful design that is different from the lighting.

第２の加飾層１５の観察者６側の面にのうち第３の反射層１３の開口部に略対応する位置に透明加飾層１６が積層される。
透明加飾層１６はスクリーン印刷によって設けることができる。特にスクリーン印刷に限定することなく、凸版印刷、フレキソ印刷、オフセット印刷、グラビア印刷、インクジェット等を用いることができる。
透明加飾層１６には透明インキを用いるのが望ましいが、光透過性があれば透明インキに限らない。厚みに制限は無いが、５μｍ〜３０μｍにすると観察者から視認しやすい。
また、透明加飾層１６の全光線透過率は８０％以上であることが望ましい。
透明加飾層１６の全光線透過率が８０％未満である場合、光源点灯時の第３の領域３の輝度が低下し、視認を妨げてしますという弊害があるからである。
透明加飾層１６は光源６の非点灯時においては第２の加飾層１５の表面で絵柄として観察され、光源６の点灯時においては第３の反射層１３及び第２の遮光層１４の開口部を抜け、第２の加飾層１５を透過した光を透過させて絵柄として観察される。
透明加飾層１６はデザイン上必要があれば設けることができ、透明加飾層１６が無くても情報表示パネル５における他の機能には影響がない。 The transparent decorative layer 16 is laminated at a position substantially corresponding to the opening of the third reflective layer 13 on the surface of the second decorative layer 15 on the viewer 6 side.
The transparent decorative layer 16 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing.
Although it is desirable to use a transparent ink for the transparent decoration layer 16, if it has a light transmittance, it will not be restricted to a transparent ink. Although there is no restriction | limiting in thickness, if it is 5 micrometers-30 micrometers, it will be easy to visually recognize from an observer.
Further, the total light transmittance of the transparent decorative layer 16 is desirably 80% or more.
This is because when the total light transmittance of the transparent decorative layer 16 is less than 80%, the luminance of the third region 3 when the light source is turned on is lowered, which hinders visual recognition.
The transparent decorative layer 16 is observed as a pattern on the surface of the second decorative layer 15 when the light source 6 is not lit, and the third reflective layer 13 and the second light shielding layer 14 are observed when the light source 6 is lit. The light passing through the opening and passing through the second decorative layer 15 is transmitted and observed as a pattern.
The transparent decorative layer 16 can be provided if necessary in terms of design. Even if the transparent decorative layer 16 is not provided, other functions in the information display panel 5 are not affected.

次に支持体８の光源６側の積層構造について詳細に説明する。
支持体８の光源６側の面のうち第１の領域１に第１の反射層２１が配置される。また、支持体８の光源６側の面のうち、第３の領域３における第３の反射層１３の開口部に対応する位置に第４の反射層２２が配置される。
第１の反射層２１及び第４の反射層２２はスクリーン印刷によって設けることができる。特にスクリーン印刷に限定することなく、凸版印刷、フレキソ印刷、オフセット印刷、グラビア印刷、インクジェット等を用いることができる。
第１の反射層２１及び第４の反射層２２には白色インキを用いるのが望ましいが、光の反射効果、透過効果があれば白色インキに限らない。厚みに制限は無いが、５μｍ〜３０μｍにすると反射効果が出やすい。
また、第１の反射層２１及び第４の反射層２２における３８０〜７８０ｎｍの光線の反射率は２０％以上であることが望ましい。
第１の反射層２１及び第４の反射層２２における反射率が２０％未満であった場合に、第１の反射層２１及び第４の反射層２２で反射される間接光の輝度が低下し、立体感が損なわれるという弊害があるからである。
光源６が点灯した際には第２の反射層１１と第３の反射層１３で反射した光及び支持体８と第２の拡散層３２で拡散した光が第１の反射層２１に入射後に反射され、観察者から間接光として視認される。これにより、第１の領域１と第２の領域２の境界及び第１の領域１と第３の領域３の境界において立体感を感じさせる効果がある。 Next, the laminated structure on the light source 6 side of the support 8 will be described in detail.
The first reflective layer 21 is disposed in the first region 1 on the surface of the support 8 on the light source 6 side. In addition, the fourth reflective layer 22 is arranged at a position corresponding to the opening of the third reflective layer 13 in the third region 3 on the surface of the support 8 on the light source 6 side.
The first reflective layer 21 and the fourth reflective layer 22 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing.
Although it is desirable to use white ink for the first reflective layer 21 and the fourth reflective layer 22, it is not limited to white ink as long as it has a light reflection effect and a light transmission effect. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, a reflective effect will come out easily.
Moreover, it is desirable that the reflectance of light of 380 to 780 nm in the first reflective layer 21 and the fourth reflective layer 22 is 20% or more.
When the reflectivity in the first reflective layer 21 and the fourth reflective layer 22 is less than 20%, the brightness of the indirect light reflected by the first reflective layer 21 and the fourth reflective layer 22 decreases. This is because the three-dimensional effect is impaired.
When the light source 6 is turned on, the light reflected by the second reflective layer 11 and the third reflective layer 13 and the light diffused by the support 8 and the second diffusion layer 32 are incident on the first reflective layer 21. Reflected and viewed as indirect light from the observer. Thereby, there is an effect of giving a stereoscopic effect at the boundary between the first region 1 and the second region 2 and the boundary between the first region 1 and the third region 3.

第１の反射層２１及び第４の反射層２２の光源側の面に第１の遮光層２３が積層される。
第１の遮光層２３はスクリーン印刷によって設けることができる。特にスクリーン印刷に限定することなく、凸版印刷、フレキソ印刷、オフセット印刷、グラビア印刷、インクジェット等を用いることができる。
第１の遮光層２３には黒色インキを用いるのが望ましいが、遮光効果があれば黒色インキに限らない。厚みに制限は無いが、５μｍ〜３０μｍにすると遮光効果が出やすい。
第１の遮光層２３の全光線透過率は２０％以下であることが望ましい。第１の遮光層２３の全光線透過率が２０％より大きい場合、第１の遮光層２３の入射光を遮光できず、第１の領域及び第３の反射層の開口部において直接光が視認されるために間接光の視認性が低下し立体感が損なわれるという弊害があるからである。
光源６が点灯した際、第１の遮光層２３で第１の反射層２１へ向かう直接光は遮光される。それにより、他方の面側から第１の反射層２１に入射して透過する光が無くなるため、第１の領域１における間接光の視認性が高まり、第１の領域１と第２の領域２の境界及び第１の領域１と第３の領域３の境界における立体感を高める効果がある。 The first light shielding layer 23 is laminated on the light source side surfaces of the first reflective layer 21 and the fourth reflective layer 22.
The first light shielding layer 23 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing.
Although it is desirable to use black ink for the first light shielding layer 23, it is not limited to black ink as long as it has a light shielding effect. Although there is no restriction | limiting in thickness, when it is 5 micrometers-30 micrometers, the light-shielding effect will come out easily.
The total light transmittance of the first light shielding layer 23 is desirably 20% or less. When the total light transmittance of the first light-shielding layer 23 is greater than 20%, the incident light of the first light-shielding layer 23 cannot be shielded, and the direct light is visually recognized at the openings of the first region and the third reflective layer. This is because the indirect light visibility is lowered and the stereoscopic effect is impaired.
When the light source 6 is turned on, direct light traveling toward the first reflective layer 21 is blocked by the first light blocking layer 23. Thereby, since there is no light incident on and transmitted through the first reflective layer 21 from the other surface side, the visibility of indirect light in the first region 1 is increased, and the first region 1 and the second region 2 are increased. And the three-dimensional effect at the boundary between the first region 1 and the third region 3.

支持体８の光源６側の面のうち、第１の反射層２１及び第４の反射層２２が設けられていない面に光透過性着色層２４を設ける。特に第１の反射層２１及び第４の反射層２２が設けられていない面にだけ限定することはなく、第２の遮光層２３の光源６側の面にも積層されてもかまわない。
光透過性着色層２４はスクリーン印刷によって設けることができる。特にスクリーン印刷に限定することなく、凸版印刷、フレキソ印刷、オフセット印刷、グラビア印刷、インクジェット等を用いることができる。
光透過性着色層２４には光透過性のある有彩色のインキが用いられるのが望ましいが、光透過性のある有彩色の層を設けられるのであればこれに限らない。
また、光透過性着色層２４は全光線透過率が２０％以上であることが望ましい。光透過性着色層２４の全光線透過率が２０％未満の場合、第２の反射層１１及び第３の反射層１３に入射して反射され第１の領域で視認される間接光の輝度が低くなることから立体感が損なわれるという弊害があるからである。
光源６が点灯した際に光透過性着色層２４を透過した光が第２の反射層１１と第３の反射層１３で反射され、さらに支持体８と第２の拡散層３２で拡散されて第１の反射層２１に入射した後に反射され、観察者から間接光として視認されるため、間接光は光透過性着色層２４の色に依存する。光透過性着色層２４を任意の色にすることにより、文字・絵柄等が美しく表示される。 Of the surface of the support 8 on the light source 6 side, the light-transmitting colored layer 24 is provided on the surface where the first reflective layer 21 and the fourth reflective layer 22 are not provided. In particular, the surface is not limited to the surface where the first reflective layer 21 and the fourth reflective layer 22 are not provided, and may be stacked on the surface of the second light shielding layer 23 on the light source 6 side.
The light transmissive colored layer 24 can be provided by screen printing. In particular, letterpress printing, flexographic printing, offset printing, gravure printing, ink jet printing, and the like can be used without being limited to screen printing.
It is desirable to use a light-transmitting chromatic ink for the light-transmitting colored layer 24, but the present invention is not limited to this as long as a light-transmitting chromatic color layer can be provided.
Further, the light transmissive colored layer 24 preferably has a total light transmittance of 20% or more. When the total light transmittance of the light-transmitting colored layer 24 is less than 20%, the luminance of the indirect light that is incident on and reflected by the second reflective layer 11 and the third reflective layer 13 is visually recognized. This is because there is a negative effect that the stereoscopic effect is impaired due to the lowering.
When the light source 6 is turned on, the light transmitted through the light-transmissive colored layer 24 is reflected by the second reflective layer 11 and the third reflective layer 13 and further diffused by the support 8 and the second diffusion layer 32. Indirect light depends on the color of the light-transmitting colored layer 24 because it is reflected after being incident on the first reflective layer 21 and is visually recognized as indirect light by an observer. By making the light-transmitting colored layer 24 an arbitrary color, characters, designs, etc. are displayed beautifully.

また、第２の領域２に文字等意匠形状が設けられる場合、光透過性着色層２４の文字等意匠形状に対応する部分よりやや大きい領域に開口部を設けることができる。光透過性着色層２４に開口部を設けると、光源６の点灯時に直接光が光透過性着色層２４を通らないため、観察者から文字等意匠形状が第２の反射層に依存する白色の直接光として視認される。ここで、光透過性着色層２４の開口部を文字等意匠形状よりやや大きくするのは、光透過性着色層９を透過した光が文字等意匠形状の端部へ干渉することを防ぐためである。
具体的には、光透過性着色層２４の開口部は、第１の加飾層１２の開口部の外周から０．０５０ｍｍ以上外側に外周を有し、光透過性着色層２４の開口部の外周が第２の領域２と第１の領域１との境界から１．０００ｍｍ以上離れているのが望ましい。
光透過性着色層２４の開口部が第１の加飾層１２の開口部の外周から０．０５０ｍｍ以上外側にない場合、第１の加飾層１２の開口部から視認される光が、白色光でなく光透過性着色層２４を透過した有彩色の光として視認されてしまうという弊害があるからである。なお、デザイン上、第１の加飾層１２の開口部から視認される光が有彩色でよい場合は、この限りではない。
また、光透過性着色層２４の開口部の外周が第２の領域と第１の領域の境界から１．０００ｍｍ以上離れていない場合、光透過性着色層２４の開口部から第２の反射層に入射して第１の領域に反射される間接光が有彩色でなくなるという弊害があるからである。
なお、この開口部は必ず設けなければならないわけではなく、デザイン上、光源点灯時の文字等意匠形状が光透過性着色層２４の色に依存する必要があるのであれば開口部を設ける必要はない。 Further, when a design shape such as a character is provided in the second region 2, an opening can be provided in a region slightly larger than a portion corresponding to the design shape such as a character of the light-transmitting colored layer 24. When the light-transmitting colored layer 24 is provided with an opening, direct light does not pass through the light-transmitting colored layer 24 when the light source 6 is turned on. Therefore, the design shape such as letters from the observer depends on the second reflective layer. Visible as direct light. Here, the reason why the opening of the light-transmitting colored layer 24 is slightly larger than the design shape of characters and the like is to prevent the light transmitted through the light-transmitting coloring layer 9 from interfering with the end portions of the design shapes of characters and the like. is there.
Specifically, the opening of the light-transmitting colored layer 24 has an outer periphery of 0.050 mm or more from the outer periphery of the opening of the first decorative layer 12, and the opening of the light-transmitting colored layer 24 is It is desirable that the outer periphery is separated from the boundary between the second region 2 and the first region 1 by 1.000 mm or more.
When the opening of the light transmissive colored layer 24 is not more than 0.050 mm outside from the outer periphery of the opening of the first decorative layer 12, the light visible from the opening of the first decorative layer 12 is white. This is because there is an adverse effect that the light is visually recognized as chromatic light that has passed through the light-transmitting colored layer 24 instead of light. In addition, it is not this limitation when the light visually recognized from the opening part of the 1st decoration layer 12 may be chromatic color on a design.
Further, when the outer periphery of the opening of the light transmissive colored layer 24 is not separated from the boundary between the second region and the first region by 1.000 mm or more, the second reflective layer is separated from the opening of the light transmissive colored layer 24. This is because the indirect light incident on the first region and reflected by the first region is not chromatic.
This opening is not necessarily provided. If the design shape such as letters when the light source is turned on needs to depend on the color of the light-transmitting colored layer 24, it is not necessary to provide the opening. Absent.

光源６からの光はシート４の入射面より光透過性着色層２４に入射する。光透過性着色層２４を透過した光は第２の領域２及び第４の反射層２２の開口部から支持体８及び第２の拡散層３２を通って第２の反射層１１及び第３の反射層１３に入射する。この際に支持体８に拡散層を含んでいれば支持体８の透過光の一部が拡散されて第１の反射層２１、第４の反射層２２に入射する。また、第２の拡散層３２でも透過光の一部が拡散されて支持体８を再度透過して第１の反射層２１、第４の反射層２２に入射する。一方、第２の反射層１１及び第３の反射層１３の入射光はそこで反射されて第１の反射層２１、第４の反射層２２に入射する。第１の反射層２１、第４の反射層２２に入射した光はそこで反射されて第１の領域１から間接光として観察される。この時、第２の領域２の直接光は第１の加飾層１２で遮光され、第３の領域３の第１の領域１との境界の直接光は第２の遮光層１４で遮光されるために、第１の領域１の間接光の輝度と第２の領域２と第３の領域３の輝度の差が出る。それにより、第１の領域１と第２の領域２の境界及び第１の領域１と第３の領域３の境界の立体感を出すことができる。
前述の第４の反射層２２の反射光は、第３の反射層１３及び第２の遮光層１４の開口部を抜けて第２の加飾層１５と透明加飾層１６を透過して観察者７に視認される。光源６からの直接光は第１の遮光層２３及び第２の遮光層１４により遮光されるので、この明暗により第３の領域３の絵柄が表現される。 Light from the light source 6 enters the light-transmitting colored layer 24 from the incident surface of the sheet 4. The light transmitted through the light-transmitting colored layer 24 passes through the support 8 and the second diffusion layer 32 from the openings of the second region 2 and the fourth reflection layer 22, and the second reflection layer 11 and the third reflection layer 32. The light enters the reflective layer 13. At this time, if the support 8 includes a diffusion layer, part of the light transmitted through the support 8 is diffused and enters the first reflection layer 21 and the fourth reflection layer 22. In addition, part of the transmitted light is diffused also in the second diffusion layer 32, is transmitted again through the support 8, and enters the first reflection layer 21 and the fourth reflection layer 22. On the other hand, the incident light of the second reflective layer 11 and the third reflective layer 13 is reflected there and enters the first reflective layer 21 and the fourth reflective layer 22. The light incident on the first reflective layer 21 and the fourth reflective layer 22 is reflected there and observed as indirect light from the first region 1. At this time, the direct light of the second region 2 is shielded by the first decorative layer 12, and the direct light at the boundary of the third region 3 with the first region 1 is shielded by the second light shielding layer 14. Therefore, there is a difference between the luminance of the indirect light in the first region 1 and the luminance of the second region 2 and the third region 3. As a result, it is possible to produce a stereoscopic effect at the boundary between the first region 1 and the second region 2 and the boundary between the first region 1 and the third region 3.
The reflected light of the fourth reflective layer 22 described above passes through the openings of the third reflective layer 13 and the second light shielding layer 14 and passes through the second decorative layer 15 and the transparent decorative layer 16 for observation. It is visually recognized by the person 7. Since the direct light from the light source 6 is shielded by the first light shielding layer 23 and the second light shielding layer 14, the pattern of the third region 3 is expressed by this light and dark.

第１の反射層２１及び第４の反射層２２の材料、作成方法、効果は、前述した第１の実施形態の場合と同様である。 The first reflective layer 21 is disposed in the first region 1 on the surface of the support 8 on the light source 6 side. In addition, the fourth reflective layer 22 is arranged at a position corresponding to the opening of the third reflective layer 13 in the third region 3 on the surface of the support 8 on the light source 6 side.
The materials, production methods, and effects of the first reflective layer 21 and the fourth reflective layer 22 are the same as those in the first embodiment described above.

支持体８の光源６側の面のうち、第１の反射層２１及び第４の反射層２２が設けられていない面に光透過性着色層２４を設ける。特に第１の反射層２１及び第４の反射層２２が設けられていない面にだけ限定することはなく、第１の反射層２１及び第４の反射層２２の光源６側の面にも積層されてもかまわない。
光透過性着色層２４の材料、作成方法、効果は、前述した第１の実施形態の場合と同様である。 Of the surface of the support 8 on the light source 6 side, the light-transmitting colored layer 24 is provided on the surface where the first reflective layer 21 and the fourth reflective layer 22 are not provided. In particular, the surface is not limited to the surface where the first reflective layer 21 and the fourth reflective layer 22 are not provided, and is also laminated on the surface of the first reflective layer 21 and the fourth reflective layer 22 on the light source 6 side. It does not matter.
The material, production method, and effects of the light transmissive colored layer 24 are the same as those of the first embodiment described above.

光透過性着色層２４が配置された後に、第１の反射層２１及び第４の反射層２２に対応する位置に第１の遮光層２３が積層される。
第１の遮光層２３の材料、作成方法、効果は、前述した第１の実施形態の場合と同様である。 After the light transmissive colored layer 24 is disposed, the first light shielding layer 23 is laminated at a position corresponding to the first reflective layer 21 and the fourth reflective layer 22.
The material, production method, and effect of the first light shielding layer 23 are the same as those in the first embodiment described above.

光源６からの光はシート４の入射面より第１の遮光層２３の開口部を通り光透過性着色層２４に入射する。光透過性着色層２４を透過した光は第２の領域２及び第４の反射層２２の開口部から支持体８及び第２の拡散層３２を通って第２の反射層１１及び第３の反射層１３に入射する。この際に支持体８に拡散層を含んでいれば支持体８の透過光の一部が拡散されて第１の反射層２１、第４の反射層２２に入射する。また、第２の拡散層３２でも透過光の一部が拡散されて支持体８を再度透過して第１の反射層２１、第４の反射層２２に入射する。一方、第２の反射層１１及び第３の反射層１３の入射光はそこで反射されて第１の反射層２１、第４の反射層２２に入射する。第１の反射層２１、第４の反射層２２に入射した光はそこで反射されて第１の領域１から間接光として観察される。この時、第２の領域２の直接光は第１の加飾層１２で遮光され、第３の領域３の第１の領域１との境界の直接光は第２の遮光層１４で遮光されるために、第１の領域１の間接光の輝度と第２の領域２と第３の領域３の輝度の差が出る。それにより、第１の領域１と第２の領域２の境界及び第１の領域１と第３の領域３の境界の立体感を出すことができる。
前述の、第４の反射層２２の反射光は第３の反射層１３及び第２の遮光層１４の開口部を抜けて第２の加飾層１５と透明加飾層１６を透過して観察者７に視認される。光源６からの直接光は第１の遮光層２３及び第２の遮光層１４により遮光されるので、この明暗により第３の領域３の絵柄が表現される。 The light from the light source 6 enters the light-transmitting colored layer 24 from the incident surface of the sheet 4 through the opening of the first light shielding layer 23. The light transmitted through the light-transmitting colored layer 24 passes through the support 8 and the second diffusion layer 32 from the openings of the second region 2 and the fourth reflection layer 22, and the second reflection layer 11 and the third reflection layer 32. The light enters the reflective layer 13. At this time, if the support 8 includes a diffusion layer, part of the light transmitted through the support 8 is diffused and enters the first reflection layer 21 and the fourth reflection layer 22. In addition, part of the transmitted light is diffused also in the second diffusion layer 32, is transmitted again through the support 8, and enters the first reflection layer 21 and the fourth reflection layer 22. On the other hand, the incident light of the second reflective layer 11 and the third reflective layer 13 is reflected there and enters the first reflective layer 21 and the fourth reflective layer 22. The light incident on the first reflective layer 21 and the fourth reflective layer 22 is reflected there and observed as indirect light from the first region 1. At this time, the direct light of the second region 2 is shielded by the first decorative layer 12, and the direct light at the boundary of the third region 3 with the first region 1 is shielded by the second light shielding layer 14. Therefore, there is a difference between the luminance of the indirect light in the first region 1 and the luminance of the second region 2 and the third region 3. As a result, it is possible to produce a stereoscopic effect at the boundary between the first region 1 and the second region 2 and the boundary between the first region 1 and the third region 3.

図３は、本発明の第３の実施形態に係る情報表示パネル５用の積層シート４をシート延在方向に垂直な面で切った断面図である。（Ａ）は積層の順序をわかりやすくするために各層を分離してあらわしたものであり、（Ｂ）は実際に積層された状態を表したものである。
図３に示すように、積層シート４は、シートの厚さ方向からみて、第１の領域１と、第１の領域１に隣接し且つ互いに離れた、第２の領域２、第３の領域３に分かれている。
積層シート４の延在面上における第１乃至第３の領域の形状により絵柄等の意匠形状が構成されている。
なお、第２、第３の領域と離れた他の領域がさらに設けられていても構わない。その場合、第１の領域は、さらに設けた領域とも隣接する配置となる。
図３において、観察者７は光透過性の支持体８の一方の面側から目視し、光源６は支持体８の他方の面側に設置される。 FIG. 3 is a cross-sectional view of the laminated sheet 4 for the information display panel 5 according to the third embodiment of the present invention, taken along a plane perpendicular to the sheet extending direction. (A) shows each layer separated for easy understanding of the order of lamination, and (B) shows a state in which the layers are actually laminated.
As shown in FIG. 3, the laminated sheet 4 includes a first region 1, a second region 2, and a third region that are adjacent to the first region 1 and separated from each other as viewed from the thickness direction of the sheet. Divided into three.
A design shape such as a pattern is configured by the shapes of the first to third regions on the extending surface of the laminated sheet 4.
Note that other regions apart from the second and third regions may be further provided. In that case, the first region is disposed adjacent to the further provided region.
In FIG. 3, the observer 7 views from one surface side of the light-transmissive support 8, and the light source 6 is installed on the other surface side of the support 8.

支持体８の観察者６側の面のうち第１の領域１に、第１の拡散層３１、第４の加飾層１７が順に積層されている。
また、支持体８の観察者６側の面のうち第２の領域２に、第２の拡散層３２、第２の反射層１１、第２の加飾層１２が順に積層されている。
さらに、支持体８の観察者６側の面のうち第３の領域３に、第２の拡散層３２、第３の反射層１３、第２の加飾層１５、第２の遮光層１４、透明加飾層１６が順に積層されている。 A first diffusion layer 31 and a fourth decorative layer 17 are sequentially stacked in the first region 1 on the surface of the support 8 on the viewer 6 side.
In addition, the second diffusion layer 32, the second reflection layer 11, and the second decoration layer 12 are sequentially laminated in the second region 2 on the surface of the support 8 on the viewer 6 side.
Further, in the third region 3 of the surface of the support 8 on the viewer 6 side, the second diffusion layer 32, the third reflection layer 13, the second decoration layer 15, the second light shielding layer 14, The transparent decoration layer 16 is laminated | stacked in order.

支持体８の光源６側の面のうち第１の領域１に、第１の反射層２１、第１の遮光層２３、光透過性着色層２４が順に積層されている。
また、支持体８の光源６側の面のうち第２の領域２及び第３の領域に、光透過性着色層２４が設けられている。 A first reflective layer 21, a first light-shielding layer 23, and a light-transmitting colored layer 24 are sequentially laminated in the first region 1 on the surface of the support 8 on the light source 6 side.
Further, a light-transmitting colored layer 24 is provided in the second region 2 and the third region of the surface of the support 8 on the light source 6 side.

支持体８の構成、材料、作成方法、効果は、第１の実施形態の場合と同様である。   The structure, material, production method, and effect of the support 8 are the same as those in the first embodiment.

また、支持体８の観察者７側の積層構造のうち、第１の領域、第２の領域の構造は前述した第１の実施形態と同様である。   Further, in the laminated structure on the viewer 7 side of the support 8, the structures of the first region and the second region are the same as those in the first embodiment described above.

支持体８の観察者６側の面のうち第３の領域３に第２の拡散層３２が配置される。
第２の拡散層３２の材料、作成方法は、前述した第１の実施形態の場合と同様である。 The second diffusion layer 32 is disposed in the third region 3 on the surface of the support 8 on the viewer 6 side.
The material and production method of the second diffusion layer 32 are the same as those in the first embodiment described above.

第２の拡散層３２（第２の拡散層３２がない場合は支持体８）の観察者６側の面のうち第３の領域３全域に第３の反射層１３が配置される。
第３の反射層１３の材料、作成方法は、前述した第１の実施形態の場合と同様である。
ここで、第３の反射層１３における３８０〜７８０ｎｍの光線の反射率は６０％以上であり、第３の反射層１３の全光線透過率は５％以上４０％以下であることが望ましい。
第３の反射層１３の反射率が６０％未満であった場合、第３の反射層１３で反射される間接光の輝度が低下し、第１の領域１と第２の領域２の境界における立体感が損なわれるからである。また、第３の反射層１３の全光線透過率が５％未満であると、第２の遮光層１４の開口部を抜けて透明加飾層１６を透過して視認される光の輝度が低下して第３の領域３の絵柄を美しく表示できないからである。
一方、全光線透過率が４０％以上であると反射率が低下して、前述のように間接光の輝度低下による第１の領域と第２の領域の境界における立体感の低下が起こるためである。
光源６が点灯した際には第３の反射層１３で反射した光が第１の領域１の第１の反射層２１に入射し、観察者７からは間接光として視認される。この時、第３の反射層１３の幅が大きい方が第３の反射層１３で反射されて第１の領域で間接光として観察される光が多く、第１の領域１と第３の領域３の境界における立体感が高まる。 The third reflective layer 13 is disposed over the entire third region 3 of the surface of the second diffusion layer 32 (the support 8 when there is no second diffusion layer 32) on the viewer 6 side.
The material and production method of the third reflective layer 13 are the same as in the case of the first embodiment described above.
Here, the reflectance of light of 380 to 780 nm in the third reflective layer 13 is preferably 60% or more, and the total light transmittance of the third reflective layer 13 is desirably 5% or more and 40% or less.
When the reflectance of the third reflective layer 13 is less than 60%, the luminance of the indirect light reflected by the third reflective layer 13 is reduced, and the boundary between the first region 1 and the second region 2 is reduced. This is because the stereoscopic effect is impaired. Further, when the total light transmittance of the third reflective layer 13 is less than 5%, the luminance of light that is visible through the transparent decorative layer 16 through the opening of the second light shielding layer 14 is lowered. This is because the pattern of the third region 3 cannot be displayed beautifully.
On the other hand, if the total light transmittance is 40% or more, the reflectance is lowered, and as described above, the stereoscopic effect at the boundary between the first region and the second region is lowered due to the luminance reduction of the indirect light. is there.
When the light source 6 is turned on, the light reflected by the third reflective layer 13 enters the first reflective layer 21 in the first region 1 and is visually recognized by the observer 7 as indirect light. At this time, the larger the width of the third reflective layer 13 is, the more light is reflected by the third reflective layer 13 and observed as indirect light in the first region, and the first region 1 and the third region The stereoscopic effect at the boundary of 3 increases.

第３の反射層１３の観察者６側の面に第２の加飾層１５が積層される。
第２の加飾層１５の材料、作成方法は、前述した第１の実施形態の場合と同様である。
光源６の非点灯時には外光が透明加飾層１６と第２の遮光層１４の開口部を通って第２の加飾層１５で反射し、観察者７からは第２の加飾層１５の色が視認される。
一方、光源６の点灯時に透明加飾層１６が積層された第２の遮光層１４の開口部では、第２の加飾層１５が半透過性であるため、光透過性着色層２４を透過した有彩色の光が観察され、非点灯時と別の美しい意匠性を表現することができる。第２の加飾層１５がないと光源６の非点灯時に第３の反射層１３を通して光透過性着色層２４の有彩色が見えてしまうため、光源６の点灯時との意匠性の違いを表現できない。 A second decorative layer 15 is laminated on the surface of the third reflective layer 13 on the viewer 6 side.
The material of the 2nd decoration layer 15 and the preparation method are the same as that of the case of 1st Embodiment mentioned above.
When the light source 6 is not turned on, external light is reflected by the second decorative layer 15 through the openings of the transparent decorative layer 16 and the second light shielding layer 14, and the second decorative layer 15 is viewed from the observer 7. The color of is visible.
On the other hand, when the light source 6 is turned on, the second decorative layer 15 is semi-transmissive at the opening of the second light shielding layer 14 on which the transparent decorative layer 16 is laminated. The chromatic color light is observed, and a beautiful design characteristic different from that when the lamp is not lit can be expressed. Without the second decorative layer 15, the chromatic color of the light-transmitting colored layer 24 can be seen through the third reflective layer 13 when the light source 6 is not lit. I can't express it.

第２の加飾層１５の観察者７側の面に開口部を持つ第２の遮光層１４が積層される。
第２の遮光層１４の材料、作成方法は、前述した第１の実施形態の場合と同様である。
光源６が点灯した際には第２の加飾層１５を透過した光を遮光して第３の領域３における絵柄を表す。さらに、第１の領域１との境界において遮光するため、第１の領域１で視認される間接光とのコントラストを高めて立体感を高めることができる。 A second light shielding layer 14 having an opening is laminated on the surface of the second decorative layer 15 on the viewer 7 side.
The material and production method of the second light shielding layer 14 are the same as those in the first embodiment described above.
When the light source 6 is turned on, the light transmitted through the second decorative layer 15 is shielded to represent the pattern in the third region 3. Furthermore, since the light is shielded at the boundary with the first region 1, the contrast with the indirect light visually recognized in the first region 1 can be increased to enhance the stereoscopic effect.

第２の遮光層１４の配置後に第３の反射層１３の開口部に対応する位置に透明加飾層１６が積層される。
透明加飾層１６の材料、作成方法は、前述した第１の実施形態の場合と同様である。
透明加飾層１６は光源６の非点灯時においては第３の領域３の最表面で絵柄として観察され、光源６の点灯時においては第３の反射層１３の開口部を抜ける光を透過させて第３の反射層１３とともに絵柄として観察者に視認させる。
透明加飾層１６はデザイン上必要があれば設けることができ、透明加飾層１６が無くても情報表示パネル５における他の機能には影響がない。 A transparent decorative layer 16 is laminated at a position corresponding to the opening of the third reflective layer 13 after the second light shielding layer 14 is disposed.
The material and production method of the transparent decorative layer 16 are the same as in the case of the first embodiment described above.
The transparent decorative layer 16 is observed as a pattern on the outermost surface of the third region 3 when the light source 6 is not lit, and transmits light passing through the opening of the third reflective layer 13 when the light source 6 is lit. The third reflective layer 13 is visually recognized by the observer as a picture.
The transparent decorative layer 16 can be provided if necessary in terms of design. Even if the transparent decorative layer 16 is not provided, other functions in the information display panel 5 are not affected.

支持体８の光源６側の面のうち、第１の領域１に第１の反射層２１が配置される。
第１の反射層２１の材料、作成方法、効果は、前述した第１の実施形態の場合と同様である。 The first reflective layer 21 is disposed in the first region 1 on the surface of the support 8 on the light source 6 side.
The material, production method, and effects of the first reflective layer 21 are the same as those in the first embodiment described above.

第１の反射層２１の光源６側の面に第１の遮光層２３が積層される。
第１の遮光層２３の材料、作成方法、効果は、前述した図１の場合と同様である。 A first light shielding layer 23 is laminated on the surface of the first reflective layer 21 on the light source 6 side.
The material, production method, and effect of the first light shielding layer 23 are the same as those in the case of FIG.

支持体８の光源６側の面のうち、第２の領域及び第３の領域に光透過性着色層２４を設ける。特に第２の領域及び第３の領域だけ限定することはなく、第１の遮光層２３に積層されてもかまわない。
光透過性着色層２４の材料、作成方法、効果は、前述した図１の場合と同様である。 The light-transmitting colored layer 24 is provided in the second region and the third region of the surface of the support 8 on the light source 6 side. In particular, the second region and the third region are not limited, and may be stacked on the first light shielding layer 23.
The material, production method, and effects of the light transmissive colored layer 24 are the same as those in the case of FIG.

光源６からの光はシート４の入射面より光透過性着色層２４に入射する。光透過性着色層２４を透過した光は第１の遮光層２３及び第１の反射層２１の開口部から支持体８及び第２の拡散層３２を通って第２の反射層１１及び第３の反射層１３に入射する。この際に支持体８に拡散層を含んでいれば支持体８の透過光の一部が拡散されて第１の反射層２１に入射する。また、第２の拡散層３２でも透過光の一部が拡散されて支持体８を再度透過して第１の反射層２１に入射する。一方、第２の反射層１１及び第３の反射層１３の入射光はそこで反射されて第１の反射層２１に入射する。第１の反射層２１に入射した光はそこで反射されて第１の領域１から間接光として観察される。この時、第２の領域２の直接光は第１の加飾層１２で遮光され、第３の領域３の第１の領域１との境界の直接光は第２の遮光層１４で遮光されるために、第１の領域１の間接光の輝度と第２の領域２と第３の領域３の輝度の差が出る。それにより、第１の領域１と第２の領域２の境界及び第１の領域１と第３の領域３の境界の立体感を出すことができる。
また、第３の領域３において第３の反射層１３と第２の加飾層１５を透過した直接光の一部は第２の遮光層１４の開口部を抜け、透明加飾層１６を透過して美しい絵柄として視認される。 Light from the light source 6 enters the light-transmitting colored layer 24 from the incident surface of the sheet 4. The light transmitted through the light-transmitting colored layer 24 passes through the support 8 and the second diffusion layer 32 from the openings of the first light-shielding layer 23 and the first reflection layer 21, and the second reflection layer 11 and the third reflection layer 32. Is incident on the reflective layer 13. At this time, if the support 8 includes a diffusion layer, a part of the transmitted light of the support 8 is diffused and enters the first reflection layer 21. In addition, part of the transmitted light is diffused also in the second diffusion layer 32, is transmitted again through the support 8, and enters the first reflection layer 21. On the other hand, the incident light of the second reflective layer 11 and the third reflective layer 13 is reflected there and enters the first reflective layer 21. The light incident on the first reflective layer 21 is reflected there and observed as indirect light from the first region 1. At this time, the direct light of the second region 2 is shielded by the first decorative layer 12, and the direct light at the boundary of the third region 3 with the first region 1 is shielded by the second light shielding layer 14. Therefore, there is a difference between the luminance of the indirect light in the first region 1 and the luminance of the second region 2 and the third region 3. As a result, it is possible to produce a stereoscopic effect at the boundary between the first region 1 and the second region 2 and the boundary between the first region 1 and the third region 3.
Further, in the third region 3, a part of the direct light transmitted through the third reflective layer 13 and the second decorative layer 15 passes through the opening of the second light shielding layer 14 and is transmitted through the transparent decorative layer 16. And it is visually recognized as a beautiful pattern.

光源６からの光はシート４の入射面より第１の遮光層２３の開口部を通って光透過性着色層２４に入射する。光透過性着色層２４を透過した光は第１の反射層２１の開口部から支持体８及び第２の拡散層３２を通って第２の反射層１１及び第３の反射層１３に入射する。この際に支持体８に拡散層を含んでいれば支持体８の透過光の一部が拡散されて第１の反射層２１に入射する。また、第２の拡散層３２でも透過光の一部が拡散されて支持体８を再度透過して第１の反射層２１に入射する。一方、第２の反射層１１及び第３の反射層１３の入射光はそこで反射されて第１の反射層２１に入射する。第１の反射層２１に入射した光はそこで反射されて第１の領域１から間接光として観察される。この時、第２の領域２の直接光は第１の加飾層１２で遮光され、第３の領域３の第１の領域１との境界の直接光は第２の遮光層１４で遮光されるために、第１の領域１の間接光の輝度と第２の領域２と第３の領域３の輝度の差が出る。それにより、第１の領域１と第２の領域２の境界及び第１の領域１と第３の領域３の境界の立体感を出すことができる。
また、第３の領域３において第３の反射層１３と第２の加飾層１５を透過した直接光の一部は第２の遮光層１４の開口部を抜け、透明加飾層１６を透過して美しい絵柄として視認される。 Light from the light source 6 enters the light transmissive colored layer 24 from the incident surface of the sheet 4 through the opening of the first light shielding layer 23. The light that has passed through the light-transmitting colored layer 24 enters the second reflective layer 11 and the third reflective layer 13 through the support 8 and the second diffusion layer 32 from the opening of the first reflective layer 21. . At this time, if the support 8 includes a diffusion layer, a part of the transmitted light of the support 8 is diffused and enters the first reflection layer 21. In addition, part of the transmitted light is diffused also in the second diffusion layer 32, is transmitted again through the support 8, and enters the first reflection layer 21. On the other hand, the incident light of the second reflective layer 11 and the third reflective layer 13 is reflected there and enters the first reflective layer 21. The light incident on the first reflective layer 21 is reflected there and observed as indirect light from the first region 1. At this time, the direct light of the second region 2 is shielded by the first decorative layer 12, and the direct light at the boundary of the third region 3 with the first region 1 is shielded by the second light shielding layer 14. Therefore, there is a difference between the luminance of the indirect light in the first region 1 and the luminance of the second region 2 and the third region 3.

A first diffusion layer 31 of transparent ink is disposed by screen printing on a first region 1 on one side of a polycarbonate having a thickness of d as a support 8, and a fourth additive is applied to a part of the first region 1. The decorative layer 17 is laminated, the second diffusion layer 32 of transparent ink is provided in the second region 2 and the third region 3, and the second reflective layer 11 of white ink is the second of the second region 2. The first decorative layer 12 of black ink is laminated on the second reflective layer 11, and the third reflective layer 13 of white ink having an opening is formed in the third region 3. Laminated on the second diffusion layer 32, the black ink second light shielding layer 14 is laminated on the third reflective layer 13, and the gray ink second decorative layer 15 is formed on the second light shielding layer 14. After the arrangement, the transparent decorative layer 16 of the transparent ink is arranged in substantially the entire area of the third region 3. Opening of the reflective layer 13 of 3 stacked in a position substantially corresponding to the.
The first reflective layer 21 of white ink is provided in the first region 1 on the other surface side of the support 8, and the fourth reflective layer 22 of white ink is the third reflective layer in the third region 3. The first light-shielding layer 23 of black ink is laminated on the first reflective layer 21 and the fourth reflective layer 22, and the light-transmitting colored layer 24 of blue ink is provided in the first opening. After the light shielding layer 23 is provided, the first region 1, the second region 2, and the third region 3 are provided.
Then, an LED light source of 1,000 cd / m 2 serving as the light source 6 was placed on the other surface side of the information display panel 5 of the present invention, and an observer 7 on one surface side looked at the time of non-lighting and lighting.

表１に図１の構成で、支持体８の厚さｄを１ｍｍ、第３の領域３の最も狭い部分の幅ｗ３を４０ｍｍ、第２の遮光層１４の開口率ｐを０．５０、第１の領域１の最も広い部分の幅ｗ１と第２の領域２の最も狭い部分の幅ｗ２を変えた際のｗ２/ｗ１の計算結果及び光源６の非点灯時の色と点灯時の第１の領域１における色及び第１の領域１と第２の領域２の境界部分の立体感を示す。   In Table 1, the thickness d of the support 8 is 1 mm, the width w3 of the narrowest portion of the third region 3 is 40 mm, the aperture ratio p of the second light shielding layer 14 is 0.50, and the configuration of FIG. The calculation result of w2 / w1 when the width w1 of the widest portion of the region 1 of 1 and the width w2 of the narrowest portion of the second region 2 are changed, the color when the light source 6 is not lit, and the first when lit The color in the first region 1 and the stereoscopic effect at the boundary between the first region 1 and the second region 2 are shown.

なお、立体感は目視による官能評価であり、評価が３以上で合格とする。   In addition, a three-dimensional effect is sensory evaluation by visual observation, and it is set as a pass by evaluation being 3 or more.

表１から第１の領域１において、各条件で光源６の点灯時は青色が視認され、非点灯時の白色と異なることから、光源６の点灯、非点灯により色の変化を表現できていることがわかる。また、第１の領域１で十分な立体感を得るためにはｗ２/ｗ１が０．１５以上である必要があることが確認できる。ｗ１/ｗ２が０．１５未満では第２の領域２が狭いために、第２の反射層１１で拡散反射され第１の領域１に向かう光の輝度が低くなってしまうためと推測される。   From Table 1, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition, and is different from white when the light source is not turned on. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that w2 / w1 needs to be 0.15 or more in order to obtain a sufficient stereoscopic effect in the first region 1. If w1 / w2 is less than 0.15, the second region 2 is narrow, so that it is presumed that the luminance of light that is diffusely reflected by the second reflective layer 11 and goes toward the first region 1 is lowered.

表２に図１の構成で、支持体８の厚さｄを１ｍｍ、第２の領域２の最も狭い部分の幅ｗ２を２０ｍｍとし、第１の領域１の最も広い部分の幅ｗ１と第３の領域３の最も狭い部分の幅ｗ３及び第２の遮光層１４の開口率ｐを変えた際の式（７）で表わされるｋの計算結果及び光源６の非点灯時の色と点灯時の第１の領域１における色及び第１の領域１と第３の領域３の境界部分の立体感を示す。   In Table 2, the thickness d of the support 8 is 1 mm, the width w2 of the narrowest portion of the second region 2 is 20 mm, and the width w1 and the third width of the widest portion of the first region 1 are shown in Table 2. The calculation result of k expressed by Expression (7) when the width w3 of the narrowest portion of the region 3 and the aperture ratio p of the second light shielding layer 14 are changed, the color when the light source 6 is not lit and the lighting time The color in the 1st area | region 1 and the three-dimensional effect of the boundary part of the 1st area | region 1 and the 3rd area | region 3 are shown.

表２から第１の領域１において、各条件で光源６の点灯時は青色が視認され、非点灯時の白色と異なることから、光源６の点灯、非点灯により色の変化を表現できていることがわかる。また、第１の領域１で十分な立体感を得るためには、式（７）で表わされるｋの値が０．１５以上である必要があることが確認できる。ｋが０．１５未満では第３の反射層１３の面積が狭いために、第３の反射層１３で拡散反射され第１の領域１に向かう光の輝度が低くなってしまうためと推測される。   In Table 1, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition, and is different from white when the light source 6 is not lit. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Moreover, in order to obtain sufficient stereoscopic effect in the first region 1, it can be confirmed that the value of k represented by the formula (7) needs to be 0.15 or more. If k is less than 0.15, the area of the third reflective layer 13 is small, so that it is presumed that the luminance of the light that is diffusely reflected by the third reflective layer 13 and goes toward the first region 1 becomes low. .

表３に図１の構成で、第１の領域１の最も広い部分の幅ｗ１と第２の領域２の最も狭い部分の幅ｗ２と第３の領域３の最も狭い部分の幅ｗ３及び第２の遮光層１４の開口率ｐにおいて、ｗ２/ｗ１が１であり、式（７）で表わされるｋの値が１であったときに、支持体８の厚さｄとｗ２を変えた際のｄ×ｗ２の計算値及び光源６の非点灯時の色と点灯時の第１の領域１における色及び第１の領域１と第２の領域２の境界部分の立体感を示す。なお、ｄは情報表示機器筺体内の空間的な設計上の制約を受けないようにするため、０．１ｍｍ〜５．００ｍｍの範囲にしている。   In Table 3, the width w1 of the widest portion of the first region 1, the width w2 of the narrowest portion of the second region 2, the width w3 of the narrowest portion of the third region 3 and the second in the configuration of FIG. When the aperture ratio p of the light shielding layer 14 is w2 / w1 is 1 and the value of k represented by the formula (7) is 1, the thickness d and w2 of the support 8 are changed. The calculated value of d × w2, the color when the light source 6 is not lit, the color in the first region 1 when lit, and the stereoscopic effect at the boundary between the first region 1 and the second region 2 are shown. Note that d is in the range of 0.1 mm to 5.00 mm so as not to be restricted by the spatial design in the information display device housing.

表３から第１の領域１において、各条件で光源６の点灯時は青色が視認され、非点灯時の白色と異なることから、光源６の点灯、非点灯により色の変化を表現できていることがわかる。また、第１の領域１で十分な立体感を得るためにはｄ×ｗ２が１．００以上である必要があることが確認できる。ｄ×ｗ２が１．００未満では第２の反射層１１で拡散反射された光が第２の領域２の支持体８で広がる範囲が狭く、第１の領域１に向かう光の輝度が低くなってしまうためと推測される。   In Table 1, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition, and is different from white when the light source 6 is not lit. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that in order to obtain a sufficient stereoscopic effect in the first region 1, d × w2 needs to be 1.00 or more. If d × w2 is less than 1.00, the range in which the light diffusely reflected by the second reflective layer 11 spreads on the support 8 in the second region 2 is narrow, and the luminance of the light toward the first region 1 is low. It is presumed that it will end up.

表４に図１の構成で、第１の領域１の最も広い部分の幅ｗ１と第２の領域２の最も狭い部分の幅ｗ２と第３の領域３の最も狭い部分の幅ｗ３及び第２の遮光層１４の開口率ｐにおいて、ｗ２/ｗ１が１であり、式（７）で表わされるｋの値が１であったときに、支持体８の厚さｄとｗ３及びｐを変えた際の式（８）のｈの計算値及び光源６の非点灯時の色と点灯時の第１の領域１における色及び第１の領域１と第３の領域３の境界部分の立体感を示す。なお、ｄは情報表示機器筺体内の空間的な設計上の制約を受けないようにするため、０．１ｍｍ〜５．００ｍｍの範囲にしている。   In Table 4, the width w1 of the widest portion of the first region 1, the width w2 of the narrowest portion of the second region 2, the width w3 of the narrowest portion of the third region 3 in the configuration of FIG. The thickness d, w3 and p of the support 8 were changed when w2 / w1 was 1 and the value of k represented by the formula (7) was 1. The calculated value of h in Equation (8), the color when the light source 6 is not lit, the color in the first region 1 when lit, and the stereoscopic effect at the boundary between the first region 1 and the third region 3 Show. Note that d is in the range of 0.1 mm to 5.00 mm so as not to be restricted by the spatial design in the information display device housing.

表４から第１の領域１において、各条件で光源６の点灯時は青色が視認され、非点灯時の白色と異なることから、光源６の点灯、非点灯により色の変化を表現できていることがわかる。また、第１の領域１で十分な立体感を得るためには式（８）で表わされるｈの値が１．００以上である必要があることが確認できる。ｈの値が１．００未満では第３の反射層１３で拡散反射された光が第３の領域３の支持体８で広がる範囲が狭く、第１の領域１に向かう光の輝度が低くなってしまうためと推測される。   From Table 4, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition and is different from white when the light source 6 is not lit. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that the value of h represented by the formula (8) needs to be 1.00 or more in order to obtain a sufficient stereoscopic effect in the first region 1. If the value of h is less than 1.00, the range in which the light diffusely reflected by the third reflective layer 13 spreads on the support 8 in the third region 3 is narrow, and the luminance of the light toward the first region 1 is low. It is presumed that it will end up.

本発明の第２の実施例について図２の構成に沿って具体的に説明する。
支持体８として厚さｄのポリカーボネートの一方の面側の第１の領域１にスクリーン印刷で透明インキの第１の拡散層３１が配置され、第１の領域１の一部に第４の加飾層１７が積層され、透明インキの第２の拡散層３２が第２の領域２及び第３の領域３に設けられ、白インキの第２の反射層１１が第２の領域２の第２の拡散層３２に重ねられ、黒インキの第１の加飾層１２が第２の反射層１１上に積層され、開口部を持つ白インキの第３の反射層１３が第３の領域３の第２の拡散層３２に積層され、黒インキの第２の遮光層１４が第３の反射層１３の上に積層され、灰色インキの第２の加飾層１５が第２の遮光層１４の配置後に第３の領域３の略全域に配置され、透明インキの透明加飾層１６が第２の加飾層１５の配置後に第３の領域３の第３の反射層１３の開口部に略対応する位置に積層される。

そして、本発明の情報表示パネル５の他方の面側に光源６となる１，０００ｃｄ/ｍ２のＬＥＤ光源を置き、非点灯時と点灯時に一方の面側の観察者７が目視した。 A second embodiment of the present invention will be specifically described along the configuration of FIG.
A first diffusion layer 31 of transparent ink is disposed by screen printing on a first region 1 on one side of a polycarbonate having a thickness of d as a support 8, and a fourth additive is applied to a part of the first region 1. The decorative layer 17 is laminated, the second diffusion layer 32 of transparent ink is provided in the second region 2 and the third region 3, and the second reflective layer 11 of white ink is the second of the second region 2. The first decorative layer 12 of black ink is laminated on the second reflective layer 11, and the third reflective layer 13 of white ink having an opening is formed in the third region 3. Laminated on the second diffusion layer 32, the black ink second light shielding layer 14 is laminated on the third reflective layer 13, and the gray ink second decorative layer 15 is formed on the second light shielding layer 14. After the arrangement, the transparent decorative layer 16 of the transparent ink is arranged in substantially the entire area of the third region 3. Opening of the reflective layer 13 of 3 stacked in a position substantially corresponding to the.
The first reflective layer 21 of white ink is provided in the first region 1 on the other surface side of the support 8, and the fourth reflective layer 22 of white ink is the third reflective layer in the third region 3. 13 is provided in the first area 1, the second area 2 and the third area 3 after the first reflective layer 21 is provided. The first light-shielding layer 23 of black ink is laminated at a position corresponding to the first reflective layer 21 and the fourth reflective layer 22 after the light-transmitting colored layer 24 is disposed.
Then, an LED light source of 1,000 cd / m 2 serving as the light source 6 was placed on the other surface side of the information display panel 5 of the present invention, and an observer 7 on one surface side looked at the time of non-lighting and lighting.

表５に図２の構成で、支持体８の厚さｄを１ｍｍ、第３の領域３の最も狭い部分の幅ｗ３を４０ｍｍ、第２の遮光層１４の開口率ｐを０．５０、第１の領域１の最も広い部分の幅ｗ１と第２の領域２の最も狭い部分の幅ｗ２を変えた際のｗ２/ｗ１の計算結果及び光源６の非点灯時の色と点灯時の第１の領域１における色及び第１の領域１と第２の領域２の境界部分の立体感を示す。   In Table 5, the thickness d of the support 8 is 1 mm, the width w3 of the narrowest portion of the third region 3 is 40 mm, the aperture ratio p of the second light shielding layer 14 is 0.50, The calculation result of w2 / w1 when the width w1 of the widest portion of the region 1 of 1 and the width w2 of the narrowest portion of the second region 2 are changed, the color when the light source 6 is not lit, and the first when lit The color in the first region 1 and the stereoscopic effect at the boundary between the first region 1 and the second region 2 are shown.

なお、立体感は目視による官能評価であり、評価が３以上で合格とする。   In addition, a three-dimensional effect is sensory evaluation by visual observation, and it is set as a pass by evaluation being 3 or more.

表５から第１の領域１において、各条件で光源６の点灯時は青色が視認され、非点灯時の白色と異なることから、光源６の点灯、非点灯により色の変化を表現できていることがわかる。また、第１の領域１で十分な立体感を得るためにはｗ２/ｗ１が０．１５以上である必要があることが確認できる。ｗ１/ｗ２が０．１５未満では第２の領域２が狭いために、第２の反射層１１で拡散反射され第１の領域１に向かう光の輝度が低くなってしまうためと推測される。   From Table 5, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition and is different from white when the light source 6 is not lit. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that w2 / w1 needs to be 0.15 or more in order to obtain a sufficient stereoscopic effect in the first region 1. If w1 / w2 is less than 0.15, the second region 2 is narrow, so that it is presumed that the luminance of light that is diffusely reflected by the second reflective layer 11 and goes toward the first region 1 is lowered.

表６に図２の構成で、支持体８の厚さｄを１ｍｍ、第２の領域２の最も狭い部分の幅ｗ２を２０ｍｍとし、第１の領域１の最も広い部分の幅ｗ１と第３の領域３の最も狭い部分の幅ｗ３及び第２の遮光層１４の開口率ｐを変えた際の前述の式（７）のｋの計算結果及び光源６の非点灯時の色と点灯時の第１の領域１における色及び第１の領域１と第３の領域３の境界部分の立体感を示す。   2, the thickness d of the support 8 is 1 mm, the width w2 of the narrowest portion of the second region 2 is 20 mm, and the width w1 and the third width of the widest portion of the first region 1 are set. When the width w3 of the narrowest part of the region 3 and the aperture ratio p of the second light-shielding layer 14 are changed, the calculation result of k in the above formula (7), the color when the light source 6 is not lit, and the lighting time The color in the 1st area | region 1 and the three-dimensional effect of the boundary part of the 1st area | region 1 and the 3rd area | region 3 are shown.

表６から第１の領域１において、各条件で光源６の点灯時は青色が視認され、非点灯時の白色と異なることから、光源６の点灯、非点灯により色の変化を表現できていることがわかる。また、第１の領域１で十分な立体感を得るためには前述の式（７）で表わされるｋの値が０．１５以上である必要があることが確認できる。ｋの値が０．１５未満では第３の反射層１３の面積が狭いために、第３の反射層１３で拡散反射され第１の領域１に向かう光の輝度が低くなってしまうためと推測される。   From Table 6, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition, and is different from white when the light source is not turned on. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that in order to obtain a sufficient stereoscopic effect in the first region 1, the value of k represented by the above formula (7) needs to be 0.15 or more. If the value of k is less than 0.15, the area of the third reflective layer 13 is small, so it is assumed that the luminance of light that is diffusely reflected by the third reflective layer 13 and goes toward the first region 1 is lowered. Is done.

表７に図２の構成で、第１の領域１の最も広い部分の幅ｗ１と第２の領域２の最も狭い部分の幅ｗ２と第３の領域３の最も狭い部分の幅ｗ３及び第２の遮光層１４の開口率ｐにおいて、ｗ２/ｗ１が１であり、式（７）で表わされるｋの値が１であったときに、支持体８の厚さｄとｗ２を変えた際のｄ×ｗ２の計算値及び光源６の非点灯時の色と点灯時の第１の領域１における色及び第１の領域１と第２の領域２の境界部分の立体感を示す。なお、ｄは情報表示機器筺体内の空間的な設計上の制約を受けないようにするため、０．１ｍｍ〜５．００ｍｍの範囲にしている。   In Table 7, the width w1 of the widest portion of the first region 1, the width w2 of the narrowest portion of the second region 2, the width w3 of the narrowest portion of the third region 3 and the second width in the configuration of FIG. When the aperture ratio p of the light shielding layer 14 is w2 / w1 is 1 and the value of k represented by the formula (7) is 1, the thickness d and w2 of the support 8 are changed. The calculated value of d × w2, the color when the light source 6 is not lit, the color in the first region 1 when lit, and the stereoscopic effect at the boundary between the first region 1 and the second region 2 are shown. Note that d is in the range of 0.1 mm to 5.00 mm so as not to be restricted by the spatial design in the information display device housing.

表７から第１の領域１において、各条件で光源６の点灯時は青色が視認され、非点灯時の白色と異なることから、光源６の点灯、非点灯により色の変化を表現できていることがわかる。また、第１の領域１で十分な立体感を得るためにはｄ×ｗ２が１．００以上である必要があることが確認できる。ｄ×ｗ２が１．００未満では第２の反射層１１で拡散反射された光が第２の領域２の支持体８で広がる範囲が狭く、第１の領域１に向かう光の輝度が低くなってしまうためと推測される。   From Table 7, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition and is different from white when the light source 6 is not lit. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that in order to obtain a sufficient stereoscopic effect in the first region 1, d × w2 needs to be 1.00 or more. If d × w2 is less than 1.00, the range in which the light diffusely reflected by the second reflective layer 11 spreads on the support 8 in the second region 2 is narrow, and the luminance of the light toward the first region 1 is low. It is presumed that it will end up.

表８に図２の構成で、第１の領域１の最も広い部分の幅ｗ１と第２の領域２の最も狭い部分の幅ｗ２と第３の領域３の最も狭い部分の幅ｗ３及び第２の遮光層１４の開口率ｐにおいて、ｗ２/ｗ１が１であり、式（７）のｋの値が１であったときに、支持体８の厚さｄとｗ３及びｐを変えた際の前述の式（８）のｈの計算値及び光源６の非点灯時の色と点灯時の第１の領域１における色及び第１の領域１と第３の領域３の境界部分の立体感を示す。なお、ｄは情報表示機器筺体内の空間的な設計上の制約を受けないようにするため、０．１ｍｍ〜５．００ｍｍの範囲にしている。   In Table 8, the width w1 of the widest portion of the first region 1, the width w2 of the narrowest portion of the second region 2, the width w3 of the narrowest portion of the third region 3 and the second width in the configuration of FIG. In the aperture ratio p of the light shielding layer 14, when w2 / w1 is 1, and the value of k in the formula (7) is 1, the thickness d of the support 8 and w3 and p are changed. The calculated value of h in the above equation (8), the color when the light source 6 is not lit, the color in the first region 1 when lit, and the stereoscopic effect at the boundary between the first region 1 and the third region 3 Show. Note that d is in the range of 0.1 mm to 5.00 mm so as not to be restricted by the spatial design in the information display device housing.

表８から第１の領域１において、各条件で光源６の点灯時は青色が視認され、非点灯時の白色と異なることから、光源６の点灯、非点灯により色の変化を表現できていることがわかる。また、第１の領域１で十分な立体感を得るためには式（８）のｈの値が１．００以上である必要があることが確認できる。ｈの値が１．００未満では第３の反射層１３で拡散反射された光が第３の領域３の支持体８で広がる範囲が狭く、第１の領域１に向かう光の輝度が低くなってしまうためと推測される。   From Table 8, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition and is different from white when the light source 6 is not lit. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Moreover, in order to obtain sufficient stereoscopic effect in the first region 1, it can be confirmed that the value of h in the formula (8) needs to be 1.00 or more. If the value of h is less than 1.00, the range in which the light diffusely reflected by the third reflective layer 13 spreads on the support 8 in the third region 3 is narrow, and the luminance of the light toward the first region 1 is low. It is presumed that it will end up.

実施例１の表１〜表４とそれに対応する実施例２の表５〜表８は同じ結果となっている。
これは光透過性着色層２４が図１のように第１の遮光層２３の後に積層されても、図２のように第１の反射層２１の後に積層されても、第１の遮光層２３の開口部に配置されるので効果が同じなのだと考えられる。 Tables 1 to 4 of Example 1 and Tables 5 to 8 of Example 2 corresponding thereto correspond to the same results.
This is because the light-transmitting colored layer 24 is laminated after the first light-shielding layer 23 as shown in FIG. 1, or after the first reflective layer 21 as shown in FIG. It is considered that the effect is the same because it is arranged in the opening of 23.

Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that w2 / w1 needs to be 0.15 or more in order to obtain a sufficient stereoscopic effect in the first region 1.

Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that in order to obtain a sufficient stereoscopic effect in the first region 1, d × w2 needs to be 1.00 or more.

支持体８として厚さｄのポリカーボネートの一方の面側の第１の領域１にスクリーン印刷で透明インキの第１の拡散層３１が配置され、第１の領域１の一部に第４の加飾層１７が積層され、透明インキの第２の拡散層３２が第２の領域２及び第３の領域３に設けられ、白インキの第２の反射層１１が第２の領域２の第２の拡散層３２に重ねられ、黒インキの第１の加飾層１２が第２の反射層１１上に積層され、白インキの第３の反射層１３が第３の領域３の第２の拡散層３２に積層され、灰色インキの第２の加飾層１５が第３の反射層１３の上に配置され、開口部を持つ黒インキの第２の遮光層１４が第２の加飾層１５の上に積層され、透明インキの透明加飾層１６が第２の遮光層１４の配置後に第３の領域３の第２の遮光層１４の開口部に略対応する位置に積層される。
支持体８の他方の面側には白インキの第１の反射層２１が第１の領域１に設けられ、青インキの光透過性着色層２４が第１の反射層２１が設けられた後から第１の領域１、第２の領域２及び第３の領域３に設けられて、黒インキの第１の遮光層２３が光透過性着色層２４が設けられた後から第１の反射層２１に対応する位置に積層され、
そして、本発明の情報表示パネル５の他方の面側に光源６となる１，０００ｃｄ/ｍ２のＬＥＤ光源を置き、非点灯時と点灯時に一方の面側の観察者７が目視した。 A fourth embodiment of the present invention will be specifically described along the configuration of FIG.
A first diffusion layer 31 of transparent ink is disposed by screen printing on a first region 1 on one side of a polycarbonate having a thickness of d as a support 8, and a fourth additive is applied to a part of the first region 1. The decorative layer 17 is laminated, the second diffusion layer 32 of transparent ink is provided in the second region 2 and the third region 3, and the second reflective layer 11 of white ink is the second of the second region 2. The black ink first decorative layer 12 is laminated on the second reflective layer 11, and the white ink third reflective layer 13 is the second diffusion of the third region 3. The second decorative layer 15 of gray ink is disposed on the third reflective layer 13 and is laminated on the layer 32, and the second light-shielding layer 14 of black ink having an opening is the second decorative layer 15. The transparent decorative layer 16 of transparent ink is laminated on the opening of the second light shielding layer 14 in the third region 3 after the second light shielding layer 14 is arranged. It is laminated to a corresponding position.
After the first reflective layer 21 of white ink is provided in the first region 1 on the other surface side of the support 8 and the light-transmissive colored layer 24 of blue ink is provided with the first reflective layer 21 To the first region 1, the second region 2, and the third region 3, and after the first light-shielding layer 23 of black ink is provided with the light-transmitting colored layer 24, the first reflective layer is formed. Is laminated at a position corresponding to 21,
Then, an LED light source of 1,000 cd / m 2 serving as the light source 6 was placed on the other surface side of the information display panel 5 of the present invention, and an observer 7 on one surface side looked at the time of non-lighting and lighting.

表１３に図４の構成で、支持体８の厚さｄを１ｍｍ、第３の領域３の最も狭い部分の幅ｗ３を４０ｍｍ、第１の領域１の最も広い部分の幅ｗ１と第２の領域２の最も狭い部分の幅ｗ２を変えた際のｗ２/ｗ１の計算結果及び光源６の非点灯時の色と点灯時の第１の領域１における色及び第１の領域１と第２の領域２の境界部分の立体感を示す。   In Table 13, the thickness d of the support 8 is 1 mm, the width w3 of the narrowest portion of the third region 3 is 40 mm, the width w1 of the widest portion of the first region 1 and the second The calculation result of w2 / w1 when the width w2 of the narrowest part of the region 2 is changed, the color when the light source 6 is not lit, the color in the first region 1 when lit, the first region 1 and the second region The stereoscopic effect of the boundary portion of the region 2 is shown.

なお、立体感は目視による官能評価であり、評価が３以上で合格とする。   In addition, a three-dimensional effect is sensory evaluation by visual observation, and it is set as a pass by evaluation being 3 or more.

表１３から第１の領域１において、各条件で光源６の点灯時は青色が視認され、非点灯時の白色と異なることから、光源６の点灯、非点灯により色の変化を表現できていることがわかる。また、第１の領域１で十分な立体感を得るためにはｗ２/ｗ１が０．１５以上である必要があることが確認できる。ｗ２/ｗ１が０．１５未満では第２の領域２が狭いために、第２の反射層１１で拡散反射され第１の領域１に向かう光の輝度が低くなってしまうためと推測される。   From Table 13, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition and is different from white when the light source 6 is not lit. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that w2 / w1 needs to be 0.15 or more in order to obtain a sufficient stereoscopic effect in the first region 1. If w2 / w1 is less than 0.15, the second region 2 is narrow, so that it is presumed that the luminance of light that is diffusely reflected by the second reflective layer 11 and goes toward the first region 1 is lowered.

表１４に図４の構成で、支持体８の厚さｄを１ｍｍ、第２の領域２の最も狭い部分の幅ｗ２を２０ｍｍとし、第１の領域１の最も広い部分の幅ｗ１及び第３の領域３の最も狭い部分の幅ｗ３を変えた際のｗ３/ｗ１の計算結果及び光源６の非点灯時の色と点灯時の第１の領域１における色及び第１の領域１と第３の領域３の境界部分の立体感を示す。   In Table 14, the thickness d of the support 8 is 1 mm, the width w2 of the narrowest portion of the second region 2 is 20 mm, the width w1 and the third width of the widest portion of the first region 1 are shown in Table 14. The calculation result of w3 / w1 when the width w3 of the narrowest part of the region 3 is changed, the color when the light source 6 is not lit, the color in the first region 1 when lit, the first region 1 and the third The stereoscopic effect of the boundary part of the area 3 is shown.

表１４から第１の領域１において、各条件で光源６の点灯時は青色が視認され、非点灯時の白色と異なることから、光源６の点灯、非点灯により色の変化を表現できていることがわかる。また、第１の領域１で十分な立体感を得るためにはｗ３/ｗ１が０．１５以上である必要があることが確認できる。ｗ３/ｗ１が０．１５未満では第３の反射層１３の幅が狭いために、第３の反射層１３で拡散反射され第１の領域１に向かう光の輝度が低くなってしまうためと推測される。   From Table 14, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition, and is different from white when the light source is not turned on. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that w3 / w1 needs to be 0.15 or more in order to obtain a sufficient stereoscopic effect in the first region 1. If w3 / w1 is less than 0.15, the width of the third reflective layer 13 is narrow, so that it is estimated that the brightness of the light that is diffusely reflected by the third reflective layer 13 and goes to the first region 1 is lowered. Is done.

表１５に図４の構成で、第１の領域１の最も広い部分の幅ｗ１と第２の領域２の最も狭い部分の幅ｗ２及び第３の領域３の最も狭い部分の幅ｗ３において、ｗ２/ｗ１が１であり、ｗ３/ｗ１が１としたときに、支持体８の厚さｄとｗ２を変えた際のｄ×ｗ２の計算値及び光源６の非点灯時の色と点灯時の第１の領域１における色及び第１の領域１と第２の領域２の境界部分の立体感を示す。なお、ｄは情報表示機器筺体内の空間的な設計上の制約を受けないようにするため、０．１ｍｍ〜５．００ｍｍの範囲にしている。   In the configuration shown in FIG. 4, the width w1 of the widest portion of the first region 1, the width w2 of the narrowest portion of the second region 2 and the width w3 of the narrowest portion of the third region 3 in the configuration of FIG. When / w1 is 1 and w3 / w1 is 1, the calculated value of d × w2 when the thickness d and w2 of the support 8 are changed, the color when the light source 6 is not lit, and the lighting time The color in the 1st area | region 1 and the three-dimensional effect of the boundary part of the 1st area | region 1 and the 2nd area | region 2 are shown. Note that d is in the range of 0.1 mm to 5.00 mm so as not to be restricted by the spatial design in the information display device housing.

表１５から第１の領域１において、各条件で光源６の点灯時は青色が視認され、非点灯時の白色と異なることから、光源６の点灯、非点灯により色の変化を表現できていることがわかる。また、第１の領域１で十分な立体感を得るためにはｄ×ｗ２が１．００以上である必要があることが確認できる。ｄ×ｗ２が１．００未満では第２の反射層１１で拡散反射された光が第２の領域２の支持体８で広がる範囲が狭く、第１の領域１に向かう光の輝度が低くなってしまうためと推測される。   From Table 15, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition, and is different from white when the light source 6 is not lit. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. Further, it can be confirmed that in order to obtain a sufficient stereoscopic effect in the first region 1, d × w2 needs to be 1.00 or more. If d × w2 is less than 1.00, the range in which the light diffusely reflected by the second reflective layer 11 spreads on the support 8 in the second region 2 is narrow, and the luminance of the light toward the first region 1 is low. It is presumed that it will end up.

表１６に図４の構成で、第１の領域１の最も広い部分の幅ｗ１と第２の領域２の最も狭い部分の幅ｗ２及び第３の領域３の最も狭い部分の幅ｗ３において、ｗ２/ｗ１が１であり、ｗ３/ｗ１が１としたときに、支持体８の厚さｄとｗ３を変えた際のｄとｗ３の値及び光源６の非点灯時の色と点灯時の第１の領域１における色及び第１の領域１と第３の領域３の境界部分の立体感を示す。なお、ｄは情報表示機器筺体内の空間的な設計上の制約を受けないようにするため、０．１ｍｍ〜５．００ｍｍの範囲にしている。 In the configuration shown in FIG. 4, in the width w1 of the widest portion of the first region 1, the width w2 of the narrowest portion of the second region 2, and the width w3 of the narrowest portion of the third region 3, w2 When / w1 is 1 and w3 / w1 is 1, the values of d and w3 when the thicknesses d and w3 of the support 8 are changed, the color when the light source 6 is not lit and the first value when lit 1 shows the color in the first region 1 and the stereoscopic effect at the boundary between the first region 1 and the third region 3. Note that d is in the range of 0.1 mm to 5.00 mm so as not to be restricted by the spatial design in the information display device housing.

表１６から第１の領域１において、各条件で光源６の点灯時は青色が視認され、非点灯時の白色と異なることから、光源６の点灯、非点灯により色の変化を表現できていることがわかる。また、第１の領域１で十分な立体感を得るためにはｄ×ｗ３が５．００以上である必要があることが確認できる。ｄ×ｗ３が５．００未満では第３の反射層１３で拡散反射された光が第３の領域３の支持体８で広がる範囲が狭く、第１の領域１に向かう光の輝度が低くなってしまうためと推測される。 In Table 16, in the first region 1, blue is visually recognized when the light source 6 is turned on under each condition, and is different from white when the light source is not turned on. Therefore, a change in color can be expressed by turning on and off the light source 6. I understand that. In order to obtain a sufficient stereoscopic effect in the first region 1, d × w3 is 5 . It can be confirmed that it is necessary to be over 00. d × w3 is 5 . If it is less than 00, the range in which the light diffusely reflected by the third reflective layer 13 spreads on the support 8 in the third region 3 is narrow, and the brightness of the light toward the first region 1 is assumed to be low. The

実施例３の表９〜表１２とそれに対応する実施例４の表１３〜表１６は同じ結果となっている。これは光透過性着色層２４が図３のように第１の遮光層２３の後に積層されても、図４のように第１の反射層２１の後に積層されても、第１の遮光層２３の開口部に配置されるので効果が同じなのだと考えられる。   Tables 9 to 12 of Example 3 and Tables 13 to 16 of Example 4 corresponding thereto correspond to the same results. Even if the light-transmitting colored layer 24 is laminated after the first light-shielding layer 23 as shown in FIG. 3 or after the first reflective layer 21 as shown in FIG. It is considered that the effect is the same because it is arranged in the opening of 23.

前記実施例のシート４を用いた情報表示パネル５において、光源６を点灯させることにより、文字・絵柄等に相当する第１の領域１に立体感を生じさせるとともに、光源６の点灯時と非点灯時とに色変化をつけて文字・絵柄を美しく表現することができた。   In the information display panel 5 using the sheet 4 of the above-described embodiment, the light source 6 is turned on to produce a three-dimensional effect in the first region 1 corresponding to characters, pictures and the like, and when the light source 6 is turned on and off. I was able to express the characters and designs beautifully by changing the color when the lamp was lit.

実施例１乃至４で作製した情報表示パネルを背面に光源を、前面の観察者側に樹脂製カバーを備えた輸送機器に用いた。   The information display panels produced in Examples 1 to 4 were used for transportation equipment including a light source on the back and a resin cover on the front observer side.
