Description

この発明は、テレビなどの映像機器、コンピューター、その他電子機器で使用されるディスプレイなどの画像表示装置に関し、更には、それら画像表示装置を製造する方法に関するものである。   The present invention relates to an image display device such as a display used in video equipment such as a television, a computer, and other electronic devices, and further relates to a method of manufacturing the image display device.

テレビなどの映像機器、或いはコンピューター、携帯電話、各種情報機器等に使用されるディスプレイとして、映像や情報を表示し、或いは入力操作を行うための画像表示装置が使用されている。
この画像表示装置としては、液晶を使用したもの、プラズマ方式を採用したもの、有機エレクトロルミネッセンスを使用したもの、ＣＲＴ方式によるもの、フィールドエミッション方式を採用したものなど様々なものがある。 2. Description of the Related Art Image displays for displaying video and information or performing input operations are used as displays used in video devices such as televisions, computers, mobile phones, various information devices, and the like.
There are various types of image display devices such as those using liquid crystal, those employing a plasma method, those employing organic electroluminescence, those employing a CRT method, those employing a field emission method.

図６に示すのは、この画像表示装置のひとつの例であるが、画像表示装置ａの表面を覆う透明パネルｂと、液晶などをその下に備える画像表示パネルｃとの間には、薄い空気層ｄが存在していた。
この空気層ｄがあると、画像表示装置ａからの光が、透明パネルｂの裏面にて反射して、その反射光が強いと、周囲の景観の映り込みが生じたり、画像が白っぽくなったりして、画像の視認性が低下する場合があった。 FIG. 6 shows an example of this image display device. However, the image display device is thin between a transparent panel b covering the surface of the image display device a and an image display panel c provided with liquid crystal or the like below. An air layer d was present.
If the air layer d is present, the light from the image display device a is reflected on the back surface of the transparent panel b, and if the reflected light is strong, the surrounding landscape may be reflected or the image may become whitish. As a result, the visibility of the image may be reduced.

これらの画像表示装置の課題を解決するために、特開２００３−２９５７８０号公報（特願２００２−９７７００）に記載された発明が開発されている。当該発明は、透明パネルと画像表示パネルとの間に、透明パネルの光屈折率とほぼ近い屈折率を有するシリコーンなどの透明ゲルを充填して、屈折によるこの光の反射を少なくし、画像の映りをより良好にしようとするものである。   In order to solve the problems of these image display devices, an invention described in Japanese Patent Application Laid-Open No. 2003-295780 (Japanese Patent Application No. 2002-97700) has been developed. In the invention, between the transparent panel and the image display panel, a transparent gel such as silicone having a refractive index approximately similar to the optical refractive index of the transparent panel is filled, so that reflection of this light due to refraction is reduced. It tries to improve the reflection.

しかしながら、同公報に記載された発明では、画像表示パネル上に形成した箱型の空間の中に透明ゲルを流し込むように方法で充填するため、空気の逃げる路がなくて、その上に透明パネルを置いたとき、透明パネルの下に空気が気泡となって残ることがあった。
この気泡は、前記した空気層と同様に、画像の映りを悪くする原因となっていた。 However, in the invention described in the publication, since the transparent gel is filled by the method so as to flow into the box-shaped space formed on the image display panel, there is no path for air to escape, and the transparent panel is formed thereon. In some cases, air may remain as bubbles under the transparent panel.
Similar to the air layer described above, the bubbles caused the image to deteriorate.

また、透明パネルを透明ゲル上に載せるとき、ゲルが流動的なものであるため、透明パネルの位置がズレることがあり、位置決めが極めて困難であった。
特開２００３−２９５７８０号公報 Further, when the transparent panel is placed on the transparent gel, the gel is fluid, so that the position of the transparent panel may be displaced, and positioning is extremely difficult.
JP 2003-295780 A

解決しようとする課題は、透明パネルと画像表示部パネルとの間に透明材料を充填するとき、気泡が生じることであり、また、パネルの位置決めが困難なことである。   The problem to be solved is that bubbles are generated when a transparent material is filled between the transparent panel and the image display unit panel, and the positioning of the panel is difficult.

平行に向き合う透明パネルと画像表示部側パネルとの間に、
画像表示部側パネルの四周縁部に対応する位置の透明パネル表面に、粘性を有するとともに、外周と連通する切欠き部を設けたスペーサを配し、
このスペーサに囲まれた空間に紫外線又は熱硬化樹脂を充填し、
その後、透明パネルに画像表示部側パネルの表面と密着させて透明パネルと画像表示部側パネルとを貼り合わせ、

更には、紫外線又は熱硬化樹脂は、透明パネルと画像表示部側パネルとの間の空間から溢れる余剰分を、スペーサの切欠き部から除去することも採用できる。 In addition, a method for manufacturing an image display device according to the present invention includes:
In image display devices such as video equipment and electronic equipment,

この発明に係る画像表示装置は、以下の効果を得ることができる。
＜イ＞透明パネルと画像表示部側パネルとの間に粘性を有するスペーサを配して両者を合わせるため、スペーサの粘性によって位置決めが容易に行え、両パネルを正確な位置にて接着可能となる。
＜ロ＞スペーサには切欠きが設けてあるため、余剰の樹脂をこの切欠きから溢れ出させるようにして、両パネルの間に充満させ、気泡が生じないようにすることができる。 The image display apparatus according to the present invention can obtain the following effects.
<A> Since a spacer having viscosity is arranged between the transparent panel and the image display unit side panel so as to match the both, positioning can be easily performed by the viscosity of the spacer, and both panels can be bonded at an accurate position. .
<B> Since the notch is provided in the spacer, it is possible to allow excess resin to overflow from the notch and to be filled between both panels so that no bubbles are generated.

この発明に係る画像表示装置の製造方法は、前記した装置によって得られる効果の他、以下のような別個の効果も得ることができる。

＜ｂ＞透明パネル上に充填した紫外線又は熱硬化樹脂は、切欠き部方向へ伸ばすようにして全体に均すため、両パネルの間の隅々に樹脂が充満し易く、また切欠き部から余剰分を溢れ出させたとき、空気の除去も良好に行われる。
＜ｃ＞透明パネルと画像表示部側パネルとを、両面から加圧して圧着した状態で内部の硬化樹脂を硬化させるため、表面が平滑で、全体の厚みも均一な画像表示装置となる。 The method for manufacturing an image display device according to the present invention can obtain the following separate effects in addition to the effects obtained by the above-described device.
<a> Since the transparent panel is inverted and the image display unit side panel is bonded in an inverted state, ultraviolet rays or thermosetting resin is brought into close contact with the surface of the image display unit side panel due to gravity, and bubbles are less likely to be generated.
<B> The ultraviolet or thermosetting resin filled on the transparent panel is smoothed out as it extends in the direction of the notch, so that the resin is easily filled in the corners between both panels. When the excess is overflowed, the air is well removed.
<C> Since the internal cured resin is cured in a state where the transparent panel and the image display unit side panel are pressed and pressed from both sides, the image display device has a smooth surface and a uniform overall thickness.

The spacer 3 is a viscous member, and a double-sided tape is suitable, but other paints, solid adhesives, and the like can be employed.
The spacers 3 are arranged on the four sides of the surface of the transparent panel 1 which corresponds to the peripheral edge of the facing image display unit side panel 2. As shown in the figure, the spacers 3 are respectively attached to positions corresponding to the four circumferences of the image display unit panel 2, and a notch 4 is formed between the end portions of each spacer 3 with a space therebetween.

次に、画像表示装置の製造方法について説明する。
＜１＞硬化樹脂の流し込み
図１に示すのは、透明パネル１の表面、つまりは画像表示部側パネル２と向き合う面の中心となる部分に、硬化樹脂５を流し込んだ例である。
硬化樹脂５は、相当な粘性を有しており、容易には四方へ広まらない。 Next, a method for manufacturing the image display device will be described.
<1> Pouring of cured resin FIG. 1 shows an example in which the cured resin 5 is poured into the surface of the transparent panel 1, that is, the center of the surface facing the image display unit side panel 2.
The cured resin 5 has a considerable viscosity and does not easily spread in all directions.

＜２＞硬化樹脂の均し
透明パネル１上の硬化樹脂５表面を、均す。樹脂５は、刷毛やヘラによって表面を均し、中心から四隅にある切欠き部４方向へ向かって均すようにする。すなわち、スペーサ３に囲まれた方形の空間にて、樹脂５を対角線方向へ均して、樹脂５の盛りをほぼ均一にする。 <2> Leveling of cured resin The surface of the cured resin 5 on the transparent panel 1 is leveled. The surface of the resin 5 is leveled with a brush or a spatula so as to be leveled from the center toward the notches 4 at the four corners.

The resin 5 descends due to its own weight, and is in close contact with the surface of the image display unit side panel 2 so that no bubbles are generated.

＜６＞余剰樹脂の溢れ出し
透明パネル１と画像標示部側パネル２とを接着したとき、その間に樹脂５が充満し、余剰の樹脂５は、四方にある切欠き部４からパネル１・２によって囲まれた空間から外へ溢れ出る。このとき、間の空気は余剰の樹脂５と一緒に切欠き部４から排出され、両パネル１・２の間にて気泡が生じない。 <6> Overflow of surplus resin When the transparent panel 1 and the image marking unit side panel 2 are bonded, the resin 5 is filled between them, and the surplus resin 5 is transferred from the cutouts 4 on the four sides to the panels 1 and 2. It overflows outside from the space surrounded by. At this time, the air in between is discharged from the cutout portion 4 together with the excess resin 5, and no bubbles are generated between the panels 1 and 2.

＜７＞両パネルの圧着
以上のようにして合わせた両パネル１・２を、その両側から板材７・８によって挟み込み、圧力を与えてパネル１・２の表面の傾きや凹凸を均して平滑に整える。
このとき、透明パネル１を押さえる板材７としては、紫外線を透過させる透明プラスチック板等が採用できる。 <7> Crimping of both panels The panels 1 and 2 combined as described above are sandwiched by the plate materials 7 and 8 from both sides, and pressure is applied to smooth the surface inclination and unevenness of the panels 1 and 2. To arrange.
At this time, as the plate member 7 for holding the transparent panel 1, a transparent plastic plate or the like that transmits ultraviolet rays can be employed.

＜８＞紫外線または熱の照射
板材７の上から紫外線又は熱９を照射して、硬化樹脂５を硬化させる。
板材７を透明プラスチック板とすると、紫外線は板材７を透過する。 <8> Irradiation of UV or heat UV light or heat 9 is applied from above the plate material 7 to cure the cured resin 5.
When the plate material 7 is a transparent plastic plate, the ultraviolet rays are transmitted through the plate material 7.
