Description

表示装置Display device
　本発明は、例えば自動車等の各種車両に搭載される表示装置に関するものである。  The present invention relates to a display device mounted on various vehicles such as automobiles. The
　従来より、この種の表示装置にあっては、例えば下記特許文献１に記載されているものが知られている。この特許文献１に記載の表示装置は、平面ディスプレイとしての表示部（表示手段）と、この表示部の前方側を覆う光透過性で平板状の保護部材と、表示部と保護部材との間に設けられる板状部材としての表示板とを備えている。 Conventionally, as a display device of this type, for example, one described in Patent Document 1 below is known. The display device described in Patent Document 1 is between a display unit (display means) as a flat display, a light-transmitting flat plate-shaped protective member that covers the front side of the display unit, and the display unit and the protective member. It is provided with a display plate as a plate-shaped member provided in.
　表示板は、薄板状に形成された光透過性の基材と、この基材の裏面において、表示部の表示領域を除いた箇所に印刷形成された黒色の遮光層とを有している。これにより基材の裏面には、遮光層が形成されない矩形の抜き印刷部（透視部）が設けられることになる。そして、表示装置を視認する視認者は、前記表示領域に表示される表示情報を保護部材及び前記抜き印刷部越しに視認可能となっている。一方で、下記特許文献２には、表示装置の外観品質を向上させるために表示装置の最表面に設置される保護部材をフラットな平板状ではなく湾曲させた構成が開示されている。 The display board has a light-transmitting base material formed in the shape of a thin plate, and a black light-shielding layer printed on the back surface of the base material except for the display area of the display unit. As a result, a rectangular punch-out printing portion (perspective portion) on which a light-shielding layer is not formed is provided on the back surface of the base material. Then, a viewer who visually recognizes the display device can visually recognize the display information displayed in the display area through the protective member and the blank printing unit. On the other hand, Patent Document 2 below discloses a configuration in which the protective member installed on the outermost surface of the display device is curved instead of a flat flat plate in order to improve the appearance quality of the display device.

A convex curved surface portion that is convex toward the direction is provided, and the boundary portion provided at the plate-shaped member portion corresponding to the second display portion is a third and third facing portion extending along the vehicle width direction of the vehicle. The third and fourth boundaries are configured to include a curved shape that bulges away from the second virtual horizontal line along the vehicle width direction across the second display. It is characterized by that.
　また本発明は、前記視認者の目の位置から近い位置にある前記第１の境界線の曲率は、前記視認者の目の位置から遠い位置にある前記第２の境界線の曲率よりも小さいことを特徴とする。 Further, in the present invention, the curvature of the first boundary line located near the position of the eyes of the viewer is smaller than the curvature of the second boundary line located far from the position of the eyes of the viewer. It is characterized by that.
　また本発明は、前記視認者の目の位置から近い位置にある前記第３の境界線の曲率は、前記視認者の目の位置から遠い位置にある前記第４の境界線の曲率よりも小さいことを特徴とする。 Further, in the present invention, the curvature of the third boundary line located near the position of the eyes of the viewer is smaller than the curvature of the fourth boundary line located far from the position of the eyes of the viewer.

　以下、本発明の一実施形態について添付図面を用いて説明する。  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. The
　本実施形態の一実施形態による表示装置Ｄは、例えば自動車の運転席前方にあるインストルメントパネル（以下、インパネと言う）に設けられ、車両に関する情報（以下、車両情報と言う。）だけでなく、当該車両情報以外の情報（例えば娯楽情報）もユーザ（運転者を含む車両の搭乗者）に表示する。 The display device D according to one embodiment of the present embodiment is provided, for example, on an instrument panel (hereinafter referred to as an instrument panel) in front of the driver's seat of an automobile, and is provided not only with information on the vehicle (hereinafter referred to as vehicle information) but also with information about the vehicle (hereinafter referred to as vehicle information). , Information other than the vehicle information (for example, entertainment information) is also displayed to the user (passenger of the vehicle including the driver).
　以下では、表示装置Ｄ（後述する複数の表示部）を視認するユーザ側（視認者側）を前方とし、表示装置Ｄ（前記複数の表示部）を視認するユーザ側とは反対側である反視認者側を後方とし、適宜の説明を行う。 In the following, the user side (viewer side) who visually recognizes the display device D (the plurality of display units described later) is the front side, and the opposite side is the opposite side to the user side who visually recognizes the display device D (the plurality of display units). The viewer side will be the rear, and appropriate explanations will be given.
　表示装置Ｄは、図１、図２に示すように、表示手段１０と、保護部材としての透光性カバー２０と、板状部材３０と、インナーケース４０と、回路基板５１～５３と、基板保持体６０と、アウターケース７０とを備える。表示装置Ｄは、図１に示すように、例えば左右方向（つまり車両の車幅方向）である矢印Ｘ方向に沿い長尺の矩形状をなしている。 As shown in FIGS. 1 and 2, the display device D includes a display means 10, a translucent cover 20 as a protective member, a plate-shaped member 30, an inner case 40, circuit boards 51 to 53, and a substrate. A holding body 60 and an outer case 70 are provided. As shown in FIG. 1, the display device D has a long rectangular shape along the arrow X direction, which is, for example, the left-right direction (that is, the vehicle width direction).
　表示手段１０は、間隔を空けて隣り合う複数の表示部を有し、計器表示部１１と、多機能表示部１２と、ミラー表示部１３とから構成される。以下、これら表示部１１～１３を纏めて「複数の表示部」とも言う。 The display means 10 has a plurality of display units adjacent to each other at intervals, and is composed of an instrument display unit 11, a multifunction display unit 12, and a mirror display unit 13. Hereinafter, these display units 11 to 13 are collectively referred to as "plurality of display units".
　計器表示部１１は、表示装置Ｄの中央部に位置し、車速、エンジン回転数等の車両に関する計測量を表示する表示媒体である。計器表示部１１は、例えば正面視で矩形状をなすＴＦＴ（Thin Film Transistor）型の液晶ディスプレイとして構成される。液晶ディスプレイは、ここでの詳細図示は省略するが、液晶パネルや当該液晶パネルを背後から照明するバックライト等を有して構成される。バックライトは、例えばＬＥＤ（Light Emitting Diode）やＬＥＤが発した光を液晶ディスプレイ側に導く導光部材等から構成される。計器表示部１１は、平面状の前面１１ａに画像を表示する平面ディスプレイであり、後述する特許請求の範囲に記載された第１の表示部に相当する。 The instrument display unit 11 is located in the center of the display device D and is a display medium that displays measured quantities related to the vehicle such as vehicle speed and engine speed. The instrument display unit 11 is configured as, for example, a TFT (Thin Film Transistor) type liquid crystal display having a rectangular shape when viewed from the front. Although detailed illustration is omitted here, the liquid crystal display includes a liquid crystal panel, a backlight that illuminates the liquid crystal panel from behind, and the like. The backlight is composed of, for example, an LED (Light Emitting Diode), a light guide member that guides the light emitted by the LED to the liquid crystal display side, and the like. The instrument display unit 11 is a flat surface display that displays an image on a flat front surface 11a, and corresponds to the first display unit described in the claims described later.
　多機能表示部１２は、計器表示部１１よりも車両の中心寄りに位置し、種々の情報を表示可能なＣＩＤ（Center Information Display）として構成される。なお、本実施形態の場合、表示装置Ｄは、左ハンドル車用のものであるため、表示装置Ｄの右側が車両の中心側となる。 The multifunction display unit 12 is located closer to the center of the vehicle than the instrument display unit 11 and is configured as a CID (Center Information Display) capable of displaying various information. In the case of the present embodiment, since the display device D is for a left-hand drive vehicle, the right side of the display device D is the center side of the vehicle.
　多機能表示部１２は、例えば正面視で矩形状をなすＴＦＴ型の液晶ディスプレイから構成される。例えば、多機能表示部１２の前面側には、図示しない静電容量式のセンサシートが設けられている。このセンサシートは、透光性カバー２０のうち前後方向において多機能表示部１２と対向する部分（後述する凸曲面部２２）の前面に対してユーザの手が触れることでなされるタッチ操作を検出可能に構成される。 The multifunction display unit 12 is composed of, for example, a TFT-type liquid crystal display having a rectangular shape when viewed from the front. For example, a capacitance type sensor sheet (not shown) is provided on the front side of the multifunction display unit 12. This sensor sheet detects a touch operation performed by a user's hand touching the front surface of a portion (convex curved surface portion 22 described later) facing the multifunction display unit 12 in the front-rear direction of the translucent cover 20. Possible to be configured.
　多機能表示部１２は、このセンサシートで検出されたタッチ操作に応じて、カーナビゲーション情報、娯楽情報、バックモニタ情報等の各種情報を表示可能となっている。多機能表示部１２は、平面状の前面１２ａに画像を表示する平面ディスプレイである。なお、ここでのセンサシートは、透光性カバー２０（前記凸曲面部２２）の背面に設けられる（貼り付けられる）が、場合によっては多機能表示部１２の前面１２ａに設けてもよい。 The multifunction display unit 12 can display various information such as car navigation information, entertainment information, and back monitor information in response to the touch operation detected by this sensor sheet. The multifunction display unit 12 is a flat display that displays an image on a flat front surface 12a. The sensor sheet here is provided (attached) on the back surface of the translucent cover 20 (the convex curved surface portion 22), but may be provided on the front surface 12a of the multifunction display unit 12 in some cases.
　ミラー表示部１３は、計器表示部１１よりも左側に位置し、サイドミラーの反射像を模した画像を表示する。具体的に、ミラー表示部１３は、図示しないサイドカメラにより撮影され、車両の左側後方の風景を示すサイドミラー画像を表示する。ミラー表示部１３は、例えば正面視で矩形状をなすＴＦＴ型の液晶ディスプレイから構成される。ミラー表示部１３は、平面状の前面１３ａに画像を表示する平面ディスプレイである。なお、多機能表示部１２（あるいはミラー表示部１３）は、後述する特許請求の範囲に記載された第２の表示部に相当する。 The mirror display unit 13 is located on the left side of the instrument display unit 11 and displays an image imitating the reflected image of the side mirror. Specifically, the mirror display unit 13 displays a side mirror image taken by a side camera (not shown) and showing a landscape on the left rear side of the vehicle. The mirror display unit 13 is composed of, for example, a TFT-type liquid crystal display having a rectangular shape when viewed from the front. The mirror display unit 13 is a flat display that displays an image on a flat front surface 13a. The multifunctional display unit 12 (or mirror display unit 13) corresponds to the second display unit described in the claims described later.
　図２に示すように、計器表示部１１の前面１１ａは、多機能表示部１２の前面１２ａ及びミラー表示部１３の前面１３ａよりも後方に位置する。また、多機能表示部１２の前面１２ａは、計器表示部１１の前面１１ａに対して図２における反時計回りに傾いている。また、ミラー表示部１３の前面１３ａは、計器表示部１１の前面１１ａに対して図２における時計回りに傾いている。また、これら複数の表示部は、左右方向において隣り合うもの同士が隙間を空けて配列されている。 As shown in FIG. 2, the front surface 11a of the instrument display unit 11 is located behind the front surface 12a of the multifunction display unit 12 and the front surface 13a of the mirror display unit 13. Further, the front surface 12a of the multifunction display unit 12 is tilted counterclockwise in FIG. 2 with respect to the front surface 11a of the instrument display unit 11. Further, the front surface 13a of the mirror display unit 13 is tilted clockwise in FIG. 2 with respect to the front surface 11a of the instrument display unit 11. Further, in these plurality of display units, adjacent ones in the left-right direction are arranged with a gap between them.
　透光性カバー２０は、図２に示すように、複数の表示部を前面側から覆う光透過性で曲面状の板材で構成される。透光性カバー２０は、例えば表示装置Ｄが搭載される車両のインパネのデザインに合わせた曲面状の板状部である。 As shown in FIG. 2, the translucent cover 20 is composed of a light-transmitting curved plate material that covers a plurality of display portions from the front side. The translucent cover 20 is, for example, a curved plate-shaped portion that matches the design of the instrument panel of the vehicle on which the display device D is mounted.
　透光性カバー２０は、曲面形状に形成された部分として、凹曲面部２１と、凸曲面部２２、２３とを有する。凹曲面部２１は、計器表示部１１と前後方向において対向し、後方に向かって凹む曲面形状を有している。凸曲面部２２は、多機能表示部１２と前後方向において対向し、前方に向かって凸となる曲面形状を有している。凸曲面部２３は、ミラー表示部１３と前後方向において対向し、前方に向かって凸となる曲面形状を有している。 The translucent cover 20 has a concave curved surface portion 21 and convex curved surface portions 22 and 23 as portions formed in a curved surface shape. The concave curved surface portion 21 has a curved surface shape that faces the instrument display unit 11 in the front-rear direction and is recessed toward the rear. The convex curved surface portion 22 has a curved surface shape that faces the multifunction display unit 12 in the front-rear direction and becomes convex toward the front. The convex curved surface portion 23 has a curved surface shape that faces the mirror display portion 13 in the front-rear direction and becomes convex toward the front.
　板状部材３０は、複数の表示部を前面側から覆うとともに、複数の表示部と透光性カバー２０との間に設けられる板状の部材である。板状部材３０と透光性カバー２０との間には、若干の隙間が設けられている。板状部材３０は、図３、図４に示すように、複数の表示部を視認するユーザ側から複数の表示部の各々に表示される所定情報を透視可能とする透視部３１、３２、３３を有する。 The plate-shaped member 30 is a plate-shaped member that covers a plurality of display units from the front surface side and is provided between the plurality of display units and the translucent cover 20. A slight gap is provided between the plate-shaped member 30 and the translucent cover 20. As shown in FIGS. 3 and 4, the plate-shaped member 30 allows the user who visually recognizes the plurality of display units to see through the predetermined information displayed on each of the plurality of display units. Have.
　また、板状部材３０は、その母材となる光透過性の基材３０ａと、不透過部としての遮光層３０ｂとを有する（図４参照）。基材３０ａは、例えば、透光性を有する樹脂から形成された板状の部材である。 Further, the plate-shaped member 30 has a light-transmitting base material 30a as a base material thereof and a light-shielding layer 30b as an impermeable portion (see FIG. 4). The base material 30a is, for example, a plate-shaped member formed of a translucent resin.
　ここで、前述の透光性カバー２０は、例えば暗色（半透過性）の樹脂材で形成されており、光の透過率が５０％程度に設定されている。また、基材３０ａは、例えば暗色（半透過性）の樹脂材で形成されており、光の透過率が５０％程度に設定されている。このようにして、表示装置Ｄの前方からの外光の侵入を制限することで、透光性カバー２０に加えて板状部材３０を設けたことの違和感を低減することができ、表示装置Ｄの一体感を向上させることができる。なお、透光性カバー２０及び基材３０ａのそれぞれの光の透過率は任意であり、８０％や３０％等であってもよい。また、透光性カバー２０や基材３０ａの材料も任意である。例えば、透光性カバー２０は、暗色の無機ガラスから構成されてもよい。 Here, the above-mentioned translucent cover 20 is made of, for example, a dark-colored (semi-transparent) resin material, and the light transmittance is set to about 50%. Further, the base material 30a is formed of, for example, a dark-colored (semi-transparent) resin material, and the light transmittance is set to about 50%. By limiting the intrusion of external light from the front of the display device D in this way, it is possible to reduce the discomfort of providing the plate-shaped member 30 in addition to the translucent cover 20, and the display device D can be used. It is possible to improve the sense of unity. The light transmittance of each of the translucent cover 20 and the base material 30a is arbitrary, and may be 80%, 30%, or the like. Further, the material of the translucent cover 20 and the base material 30a is also arbitrary. For example, the translucent cover 20 may be made of dark-colored inorganic glass.
　また、透光性カバー２０の前面及び背面の少なくとも何れかと、基材３０ａの前面及び背面の少なくとも何れかに低反射処理を施してもよい。低反射処理としては、一例として透光性カバー２０の前面と基材３０ａの背面にＡＲ（Anti-Reflection）処理を施すとともに、透光性カバー２０の背面と基材３０ａの前面にモスアイ処理を施す構成を挙げることができる。低反射処理の方法としては、フィルム貼合、フィルムインサート成形（ＩＭＬ：Insert Molding Laminate）、スパッタリング等を用いることができる。このように反射を防止することで、透光性カバー２０に加えて板状部材３０を設けたことの違和感を低減することができ、表示装置Ｄの一体感を向上させることができる。 Further, at least one of the front surface and the back surface of the translucent cover 20 and at least one of the front surface and the back surface of the base material 30a may be subjected to a low reflection treatment. As an example of the low reflection treatment, AR (Anti-Reflection) treatment is applied to the front surface of the translucent cover 20 and the back surface of the base material 30a, and moth-eye treatment is applied to the back surface of the translucent cover 20 and the front surface of the base material 30a. The configuration to be applied can be mentioned. As a method of low reflection treatment, film bonding, film insert molding (IML: Insert Molding Laminate), sputtering and the like can be used. By preventing reflection in this way, it is possible to reduce the discomfort of providing the plate-shaped member 30 in addition to the translucent cover 20, and it is possible to improve the sense of unity of the display device D.
　遮光層３０ｂは、例えばスクリーン印刷により基材３０ａの背面に形成された黒色の印刷層である。板状部材３０における透視部３１、３２、３３の各々は、基材３０ａの遮光層３０ｂが設けられていない部分により形成される。つまり、このことは透視部３１、３２、３３は、基材３０ａが露出している基材露出部分であることを意味する。 The light-shielding layer 30b is a black printing layer formed on the back surface of the base material 30a by, for example, screen printing. Each of the fluoroscopic portions 31, 32, and 33 in the plate-shaped member 30 is formed by a portion of the base material 30a in which the light-shielding layer 30b is not provided. That is, this means that the fluoroscopic portions 31, 32, and 33 are the exposed base material portions where the base material 30a is exposed.
　なお、図４の断面図では、計器表示部１１に対応する透視部３１及び多機能表示部１２に対応する透視部３２について示したが、透視部３３についても同様である。なお、遮光層３０ｂは、基材３０ａの前面と背面の少なくとも何れかに設けることができる。また、遮光層３０ｂは、黒色以外の色を有する印刷層であってもよいし、塗布により形成されるものであってもよいし、あるいは基材３０ａに固定される遮光性シートであってもよい。 In the cross-sectional view of FIG. 4, the fluoroscopic unit 31 corresponding to the instrument display unit 11 and the fluoroscopic unit 32 corresponding to the multifunction display unit 12 are shown, but the same applies to the fluoroscopic unit 33. The light-shielding layer 30b can be provided on at least one of the front surface and the back surface of the base material 30a. Further, the light-shielding layer 30b may be a printing layer having a color other than black, may be formed by coating, or may be a light-shielding sheet fixed to the base material 30a. good.
　板状部材３０は、主に図２に示すように、本実施形態に特有の形状を有する部分として、平面部Ｐ１～Ｐ３、並びに曲面部Ｃ１、Ｃ２を有する。平面部Ｐ１～Ｐ３の各々に上述の透視部３１～３３が設けられている。 As shown mainly in FIG. 2, the plate-shaped member 30 has flat surface portions P1 to P3 and curved surface portions C1 and C2 as portions having a shape peculiar to the present embodiment. The above-mentioned fluoroscopic portions 31 to 33 are provided on each of the flat surface portions P1 to P3.
　平面部Ｐ１は、計器表示部１１と前後方向において隙間を空けて対向する部分である。平面部Ｐ１の背面と計器表示部１１の前面１１ａとは、概ね平行（丁度平行も含む。以下同様。）に設定されている。平面部Ｐ２は、多機能表示部１２と前後方向において隙間を空けて対向する部分である。平面部Ｐ２の背面と多機能表示部１２の前面１２ａとは、概ね平行に設定されている。平面部Ｐ３は、ミラー表示部１３と前後方向において隙間を空けて対向する部分である。平面部Ｐ３の背面とミラー表示部１３の前面１３ａとは、概ね平行に設定されている。 The flat surface portion P1 is a portion facing the instrument display unit 11 with a gap in the front-rear direction. The back surface of the flat surface portion P1 and the front surface 11a of the instrument display unit 11 are set to be substantially parallel (including just parallel; the same applies hereinafter). The flat surface portion P2 is a portion facing the multifunction display unit 12 with a gap in the front-rear direction. The back surface of the flat surface portion P2 and the front surface 12a of the multifunction display unit 12 are set to be substantially parallel to each other. The flat surface portion P3 is a portion facing the mirror display unit 13 with a gap in the front-rear direction. The back surface of the flat surface portion P3 and the front surface 13a of the mirror display unit 13 are set to be substantially parallel to each other.
　これら平面部Ｐ１～Ｐ３と複数の表示部の各々との隙間は、例えば１ミリメートル程度に概ね一定（丁度一定も含む。）に設定され、各隙間には、ＯＣＡ（Optical Clear Adhesive）やＯＣＲ（Optical Clear Resin）等の光硬化型接着剤ＯＢが充填されている。つまり、板状部材３０は、平面部Ｐ１の背面と計器表示部１１の前面１１ａとの隙間、平面部Ｐ２の背面と多機能表示部１２の前面１２ａとの隙間、平面部Ｐ３の背面とミラー表示部１３の前面１３ａとの隙間の各々に充填された光硬化型接着剤ＯＢによって、複数の表示部の前面側に固定されている。 The gap between the flat surface portions P1 to P3 and each of the plurality of display portions is set to be substantially constant (including just constant), for example, about 1 mm, and each gap is set to OCA (Optical Clear Adhesive) or OCR (Optical Clear Adhesive). It is filled with a photo-curing adhesive OB such as Optical Clear Resin). That is, the plate-shaped member 30 has a gap between the back surface of the flat surface portion P1 and the front surface 11a of the instrument display unit 11, a gap between the back surface of the flat surface portion P2 and the front surface 12a of the multifunction display unit 12, and the back surface of the flat surface portion P3 and a mirror. The photocurable adhesive OB filled in each of the gaps between the display unit 13 and the front surface 13a is fixed to the front surface side of the plurality of display units.
　板状部材３０と複数の表示部とは、例えば紫外線（ＵＶ）硬化型接着剤である光硬化型接着剤ＯＢを挟んで重ね合わせた後に、光を照射して接着剤を硬化させる所謂、オプティカルボンディングと称される方法で接着されている。なお、平面部Ｐ１～Ｐ３と複数の表示部の各々との隙間の設定値は任意であり、１ミリメートル以下であっても１ミリメートルよりも大きくてもよい。但し、光硬化型接着剤ＯＢを低減する観点から、当該隙間は１ミリメートル以下であることが好ましい。 The plate-shaped member 30 and the plurality of display portions are, for example, laminated with a photocurable adhesive OB which is an ultraviolet (UV) curable adhesive, and then irradiated with light to cure the adhesive, so-called optical. It is bonded by a method called bonding. The setting value of the gap between the flat surface portions P1 to P3 and each of the plurality of display units is arbitrary, and may be 1 mm or less or larger than 1 mm. However, from the viewpoint of reducing the photocurable adhesive OB, the gap is preferably 1 mm or less.
　曲面部Ｃ１は、計器表示部１１と多機能表示部１２との間の隙間を覆うとともに、計器表示部１１と多機能表示部１２とを繋ぐように形成された曲面形状を有する。具体的に、曲面部Ｃ１は、平面部Ｐ１と平面部Ｐ２とを繋ぐ部分であり、計器表示部１１の右端部前方と多機能表示部１２の左端部前方との間に位置する。 The curved surface portion C1 has a curved surface shape formed so as to cover the gap between the instrument display unit 11 and the multifunction display unit 12 and to connect the instrument display unit 11 and the multifunction display unit 12. Specifically, the curved surface portion C1 is a portion connecting the flat surface portion P1 and the flat surface portion P2, and is located between the front of the right end portion of the instrument display unit 11 and the front of the left end portion of the multifunction display unit 12.
　曲面部Ｃ２は、計器表示部１１とミラー表示部１３との間の隙間を覆うとともに、計器表示部１１とミラー表示部１３とを繋ぐように形成された曲面形状を有する。具体的に、曲面部Ｃ２は、平面部Ｐ１と平面部Ｐ３とを繋ぐ部分であり、計器表示部１１の左端部前方とミラー表示部１３の右端部前方との間に位置する。 The curved surface portion C2 has a curved surface shape formed so as to cover the gap between the instrument display unit 11 and the mirror display unit 13 and to connect the instrument display unit 11 and the mirror display unit 13. Specifically, the curved surface portion C2 is a portion connecting the flat surface portion P1 and the flat surface portion P3, and is located between the front of the left end portion of the instrument display unit 11 and the front of the right end portion of the mirror display unit 13.
　板状部材３０の平面部Ｐ１に位置する透視部３１は、透光性カバー２０の凹曲面部２１と対向する位置に設けられている。つまり、この場合、透光性カバー２０には、複数の表示部のうち計器表示部１１に対応させて後方に向けて凹む凹曲面部２１が設けられた構成となっている。 The fluoroscopic portion 31 located on the flat surface portion P1 of the plate-shaped member 30 is provided at a position facing the concave curved surface portion 21 of the translucent cover 20. That is, in this case, the translucent cover 20 is provided with a concave curved surface portion 21 that is recessed toward the rear corresponding to the instrument display unit 11 among the plurality of display units.
　そして、本例の場合、透視部３１とこの透視部３１の四方を取り囲むように設けられる遮光層３０ｂとに着目したとき、図３に示すように板状部材３０を前方から見ると、透視部３１と遮光層３０ｂとの境界部分である境界線Ｌ１の少なくとも一部が非直線形状となっている。 Then, in the case of this example, when focusing on the see-through portion 31 and the light-shielding layer 30b provided so as to surround the four sides of the see-through portion 31, when the plate-shaped member 30 is viewed from the front as shown in FIG. At least a part of the boundary line L1 which is the boundary portion between the 31 and the light-shielding layer 30b has a non-linear shape.
　より具体的には、計器表示部１１に対応した板状部材３０箇所に設けられることになる上述の境界線Ｌ１は、車両の左右方向（車幅方向）に沿って延びる相対する第１、第２の境界線としての第１、第２の横境界線Ｌ１ａ、Ｌ１ｂを備え、第１、第２の横境界線Ｌ１ａ、Ｌ１ｂは、計器表示部１１を横切る（計器表示部１１を上下に略２等分する）車幅方向に沿った第１仮想水平ラインＸ１に向かって膨らむ凹状曲線（曲線形状）を含んで構成される。これにより計器表示部１１はユーザ側から遠い奥まった位置にあるかのようにユーザ側から視認されることになる。 More specifically, the above-mentioned boundary line L1 to be provided at 30 plate-shaped members corresponding to the instrument display unit 11 is a first and a second facing line extending along the left-right direction (vehicle width direction) of the vehicle. The first and second horizontal boundary lines L1a and L1b are provided as the boundary line of 2, and the first and second horizontal boundary lines L1a and L1b cross the instrument display unit 11 (the instrument display unit 11 is abbreviated up and down). It is configured to include a concave curve (curve shape) that swells toward the first virtual horizontal line X1 along the vehicle width direction (divided into two equal parts). As a result, the instrument display unit 11 is visually recognized from the user side as if it were located at a position far from the user side.
　一方で、境界線Ｌ１のうち第１、第２の横境界線Ｌ１ａ、Ｌ１ｂを除いた第１の横境界線Ｌ１ａと第２の横境界線Ｌ１ｂとの端部同士を繋ぐ第１、第２の縦境界線Ｌ１ｃ、Ｌ１ｄは直線形状としている。つまり、第１、第２の縦境界線Ｌ１ｃ、Ｌ１ｄは、第１仮想水平ラインＸ１とは直交する方向に形成される。第１の横境界線Ｌ１ａと第２の横境界線Ｌ１ｂとは、第１、第２の縦境界線Ｌ１ｃ、Ｌ１ｄから遠ざかるに従って互いに近付くように内側に向かって膨らんでいる。なお、第１の横境界線Ｌ１ａの曲率は所定の値に設定された曲率であり、第２の横境界線Ｌ１ｂの曲率は所定の値に設定された曲率であり、ここでの第１の横境界線Ｌ１ａの曲率と第２の横境界線Ｌ１ｂの曲率とは等しい。 On the other hand, of the boundary lines L1, the first and second horizontal boundary lines L1a excluding the first and second horizontal boundary lines L1a and L1b and the second horizontal boundary lines L1b are connected to each other. The vertical boundary lines L1c and L1d of are linear. That is, the first and second vertical boundary lines L1c and L1d are formed in a direction orthogonal to the first virtual horizontal line X1. The first horizontal boundary line L1a and the second horizontal boundary line L1b bulge inward so as to approach each other as they move away from the first and second vertical boundary lines L1c and L1d. The curvature of the first horizontal boundary line L1a is the curvature set to a predetermined value, and the curvature of the second horizontal boundary line L1b is the curvature set to a predetermined value. The curvature of the horizontal boundary line L1a is equal to the curvature of the second horizontal boundary line L1b.
　このように第１、第２の横境界線Ｌ１ａ、Ｌ１ｂが凹状の曲線となっていることにより、透光性カバー２０の凹曲面部２１と同様に、板状部材３０の平面部Ｐ１も凹状に湾曲しているかのような錯覚をユーザに与えることができ、平面部Ｐ１と、透視部３１を透かして視認される計器表示部１１に曲面感を与えることができる。結果として、表示装置Ｄを一体感のある見栄えとすることができる。 Since the first and second horizontal boundary lines L1a and L1b are concave curves in this way, the flat surface portion P1 of the plate-shaped member 30 is also concave like the concave curved surface portion 21 of the translucent cover 20. It is possible to give the user the illusion that the light is curved, and it is possible to give a curved surface feeling to the flat surface portion P1 and the instrument display unit 11 which is visually recognized through the fluoroscopic unit 31. As a result, the display device D can have a cohesive appearance.
　また、板状部材３０の平面部Ｐ２に位置する透視部３２は、透光性カバー２０の凸曲面部２２と対向する位置に設けられている。つまり、この場合、透光性カバー２０には、複数の表示部のうち多機能表示部１２に対応させて前方に向けて凸となる凸曲面部２２が設けられた構成となっている。 Further, the fluoroscopic portion 32 located on the flat surface portion P2 of the plate-shaped member 30 is provided at a position facing the convex curved surface portion 22 of the translucent cover 20. That is, in this case, the translucent cover 20 is provided with a convex curved surface portion 22 that is convex toward the front corresponding to the multifunctional display unit 12 among the plurality of display units.
　そして、本例の場合、透視部３２とこの透視部３２の四方を取り囲むように設けられる遮光層３０ｂとに着目したとき、図３に示すように板状部材３０を前方から見ると、透視部３２と遮光層３０ｂとの境界部分である境界線Ｌ２の少なくとも一部が非直線形状となっている。 Then, in the case of this example, when focusing on the see-through portion 32 and the light-shielding layer 30b provided so as to surround the four sides of the see-through portion 32, when the plate-shaped member 30 is viewed from the front as shown in FIG. At least a part of the boundary line L2, which is the boundary portion between 32 and the light-shielding layer 30b, has a non-linear shape.
　より具体的には、多機能表示部１２に対応した板状部材３０箇所に設けられることになる上述の境界線Ｌ２は、前記車幅方向に沿って延びる相対する第３、第４の境界線としての第３、第４の横境界線Ｌ２ａ、Ｌ２ｂを備え、第３、第４の横境界線Ｌ２ａ、Ｌ２ｂは、多機能表示部１２を横切る（多機能表示部１２を上下に略２等分する）車幅方向に沿った第２仮想水平ラインＸ２から離れる方向へ膨らむ凸状曲線（曲線形状）を含んで構成される。これにより多機能表示部１２はユーザ側から近い位置にあるかのようにユーザ側から視認されることになる。 More specifically, the above-mentioned boundary line L2 to be provided at 30 plate-shaped members corresponding to the multifunction display unit 12 is a relative third and fourth boundary line extending along the vehicle width direction. The third and fourth horizontal boundary lines L2a and L2b are provided, and the third and fourth horizontal boundary lines L2a and L2b cross the multi-function display unit 12 (the multi-function display unit 12 is substantially 2 etc. up and down). (Divided) Consists of a convex curve (curve shape) that swells in a direction away from the second virtual horizontal line X2 along the vehicle width direction. As a result, the multifunction display unit 12 is visually recognized by the user as if it were located close to the user.
　一方で、境界線Ｌ２のうち第３、第４の横境界線Ｌ２ａ、Ｌ２ｂを除いた第３の横境界線Ｌ２ａと第４の横境界線Ｌ２ｂとの端部同士を繋ぐ第３、第４の縦境界ラインＬ２ｃ、Ｌ２ｄは直線形状としている。つまり、第３、第４の縦境界ラインＬ２ｃ、Ｌ２ｄは、第２仮想水平ラインＸ２とは直交する方向に形成される。第３の横境界線Ｌ２ａと第４の横境界線Ｌ２ｂとは、第３、第４の縦境界ラインＬ２ｃ、Ｌ２ｄから遠ざかるに従って互いに離れるように外側に向かって膨らんでいる。なお、第３の横境界線Ｌ２ａの曲率は所定の値に設定された曲率であり、第４の横境界線Ｌ２ｂの曲率は所定の値に設定された曲率であり、ここでの第３の横境界線Ｌ２ａの曲率と第４の横境界線Ｌ２ｂの曲率とは等しい。 On the other hand, of the boundary lines L2, the third and fourth horizontal boundary lines L2a excluding the third and fourth horizontal boundary lines L2a and L2b and the fourth horizontal boundary lines L2b are connected to each other. The vertical boundary lines L2c and L2d of are linear. That is, the third and fourth vertical boundary lines L2c and L2d are formed in a direction orthogonal to the second virtual horizontal line X2. The third horizontal boundary line L2a and the fourth horizontal boundary line L2b bulge outward so as to be separated from each other as the distance from the third and fourth vertical boundary lines L2c and L2d increases. The curvature of the third horizontal boundary line L2a is the curvature set to a predetermined value, and the curvature of the fourth horizontal boundary line L2b is the curvature set to a predetermined value. The curvature of the horizontal boundary line L2a is equal to the curvature of the fourth horizontal boundary line L2b.
　このように第３、第４の横境界線Ｌ２ａ、Ｌ２ｂが凸状の曲線となっていることにより、透光性カバー２０の凸曲面部２２と同様に、板状部材３０の平面部Ｐ２も凸状に湾曲しているかのような錯覚をユーザに与えることができ、平面部Ｐ２と、透視部３２を透かして視認される多機能表示部１２に曲面感を与えることができる。結果として、表示装置Ｄを一体感のある見栄えとすることができる。 Since the third and fourth horizontal boundary lines L2a and L2b are convex curves in this way, the flat surface portion P2 of the plate-shaped member 30 is also formed in the same manner as the convex curved surface portion 22 of the translucent cover 20. It is possible to give the user the illusion that it is curved in a convex shape, and it is possible to give a curved surface feeling to the flat surface portion P2 and the multifunctional display unit 12 which is visually recognized through the perspective portion 32. As a result, the display device D can have a cohesive appearance.
　インナーケース４０は、板状部材３０の背面側に位置するとともに複数の表示部を収容する樹脂ケースである。インナーケース４０において、複数の表示部を収納する部分以外の前面は、板状部材３０の形状に対応した形状で形成されている。なお、板状部材３０は、上述のように光硬化型接着剤ＯＢを介して複数の表示部の各々の前面に固定されるが、光硬化型接着剤ＯＢが充填されていない部分（例えば板状部材３０の外縁部）がインナーケース４０の前面に、接着、嵌合、螺着等の適宜固定手段により固定されていてもよい。 The inner case 40 is a resin case located on the back surface side of the plate-shaped member 30 and accommodating a plurality of display portions.
