The dial 60 is provided on the visual position EP side of the meter housing 20, and is interposed and held between the meter housing 20 and the facing member 70 in the depth direction Y. In the dial 60, a portion on which various symbols, characters, graduations and the like, various decorations and the like are drawn is exposed from the facing member 70 to the viewing position EP side, and constitutes a display surface on which various information is displayed.

  Specifically, the dial 60 is formed in a thin plate shape, and is configured to include a light shielding area 61, a design forming area 62, and a design board area 63. The dial 60 has a shape corresponding to the design pattern 62a with black ink, for example, on the base material of a polycarbonate sheet of a light-transmitting material that transmits and diffuses light of a wavelength of at least visible light region, that is, visible light. The design construction area 62 is formed by applying the hollowed out printing.

  And the display apparatus 1 for vehicles of this embodiment is provided with the design board 80 which covers the flame | frame 13d etc. of the display 13. FIG. The design plate 80 is formed in a plate shape, is provided in the design plate region 63 of the dial plate 60, and is located between the speedometer 11 and the tachometer 12. The surface on one side of the design plate 80, that is, the surface on the back side in the depth direction Y faces the image display surface 13c of the liquid crystal panel 13a. For example, in the design plate 80, the left side in the width direction X is formed in an arc along the outer shape of the speedometer 11, and the right side in the width direction X is formed in an arc along the outer shape of the tachometer 12. It is located adjacent to the total 11 and the tachometer 12. It is preferable that the design plate 80 be integrally formed with the dial plate 60. For example, the design plate 80 and the dial plate 60 are formed on a sheet of polycarbonate sheet of light transmitting material.

  The design plate 80 is a member that is disposed on the front side in the depth direction Y of the image display surface 13c of the display 13 and covers the frame 13d and the like of the display 13 in a state in which the image display surface 13c is visible. The design plate 80 makes the boundary between the image display surface 13 c and the design plate 80 inconspicuous when viewed from the visual position EP. That is, when viewed from the visual position EP, the design plate 80 makes it difficult to distinguish between the image display surface 13c of the liquid crystal panel 13a and the design plate 80, and all front sides in the depth direction Y of the design plate 80 are image display surfaces. The design is enhanced by making it visible as in 13c. Hereinafter, the configuration of the design board 80 will be described in detail.

  As shown in FIG. 3, the design plate 80 has a base 81, a first base transmitting portion 82 as a transmitting portion, a gradation portion 83, a second base transmitting portion 84, a light shielding portion 85, and the like. And a coat unit 86. The base material 81 is formed in a thin plate shape, and both sides in the width direction X are formed in an arc shape (see FIG. 2). The substrate 81 is formed of a transparent resin member having transparency to transmit light. The base material 81 is, for example, a light transmitting material that transmits visible light, and a transparent and colorless transparent resin member made of polycarbonate is used. In the base 81, for example, an anti-reflection processing unit 87 for suppressing reflection on the front side in the depth direction Y, that is, the visual position EP side, is printed flush over the entire base 81 by screen printing or the like. . As the anti-reflection processing unit 87, for example, an AR (anti-reflection) coat, an AG (anti-glare) coat, a moth-eye structure or the like is adopted.

  The first base material transmitting portion 82 is a portion that transmits light as viewed from the viewing position EP. The first base material transmitting portion 82 is a partial region of the base material 81 formed of a colorless and transparent insulating transparent resin member. The first base material transmitting portion 82 is, for example, a portion of the base material 81 which is divided into a size that fits in the image display surface 13c when viewed from the design plate 80 side in the depth direction Y. That is, the first base material transmitting portion 82 has such a size that all necessary images displayed on the image display surface 13c can be viewed as viewed from the viewing position EP and the frame of the display 13 viewed from the viewing position EP The size is such that 13 d is not visible. The first base material transmitting portion 82 is formed in, for example, a rectangular shape slightly smaller in size than the image display surface 13 c of the liquid crystal panel 13 a. The first base material transmitting portion 82 is disposed to face the front side in the depth direction Y of the image display surface 13c, that is, the visual position EP side. In the first base material transmitting portion 82, the entire periphery of the outer peripheral portion of the first base material transmitting portion 82 is adjacent to the light shielding portion 85 via the gradation portion 83. In the first base material transmitting portion 82, an overcoat portion 86 described later is formed. The first substrate transmitting portion 82 and the overcoat portion 86 constitute a display transmitting layer R1 of the design plate 80. The display transmission layer R1 transmits the light emitted from the image display surface 13c of the liquid crystal panel 13a to the viewing position EP.

  The gradation portion 83 is a portion that obscures the boundary between the first base light transmitting portion 82 and the light shielding portion 85. The gradation portion 83 is provided between the first base light transmitting portion 82 and the light shielding portion 85, and is formed of a plurality of granular dots 83a of a light shielding print layer having a light shielding property for shielding light. The light shielding print layer is formed of, for example, a black synthetic resin. In the gradation portion 83, for example, the dots 83a are printed so as to slightly protrude along the depth direction Y by inkjet printing, screen printing, or the like. The gradation portion 83 is provided on the image display surface 13 c side of the base 81. The gradation part 83 is provided between the entire periphery of the outer peripheral part of the first base material transmitting part 82 and the light shielding part 85 on the image display surface 13 c side of the base material 81. That is, on the image display surface 13 c side of the base 81, the gradation part 83 is provided adjacent to the outer peripheral part of the first base transmission part 82 so as to surround the first base transmission part 82. Specifically, the gradation portion 83 is formed in a substantially rectangular ring shape along the outer shape of the first base material transmitting portion 82. The gradation portion 83 forms a first boundary 83 b and the outer peripheral portion of the first base material transmitting portion 82, and is formed in a region outside the first boundary 83 b. The gradation part 83 is formed by changing the density per unit area of each dot 83a. The gradation portion 83 is formed, for example, such that the density of each dot 83a is sparse to high from the first boundary 83b to the outside. That is, the gradation portion 83 is formed so that the density of each dot 83 a is sparse to high from the first substrate transmitting portion 82 side toward the light shielding portion 85 side. The gradation part 83 makes the dot diameter which is the diameter of each dot 83a equal, for example, and changes the density by adjusting the space | interval of each adjacent dot 83a. The gradation unit 83 may change the density by, for example, adjusting the interval between adjacent dots 83a by changing the dot diameter of each dot 83a. The density of the dots 83a gradually increases from the side of the first substrate transmitting portion 82 toward the side of the light shielding portion 85 in the gradation portion 83. Therefore, the white color is black when the image display surface 13c is lit and not lit. It is possible to obscure the boundary between the first base light transmitting portion 82 visually recognized as and the light shielding portion 85 visually recognized as black. Here, light may leak from the gap of the liquid crystal cell of the liquid crystal panel 13a in the image display surface 13c, and this leaked light is recognized as whiteish black in order to visually recognize from the visual position EP side.

  The second substrate transmitting portion 84 is a portion which is formed at a position different from that of the first substrate transmitting portion 82, and transmits the light of each visible light source 50 for an indicator. The second base material transmitting portion 84 is formed so as to be able to visually recognize a design pattern 84 a of a vehicle including various symbols, characters, decorations, and the like. The design pattern 84a includes, for example, a notification symbol or the like for notifying a driver or the like of various information. The notification symbol is, for example, a direction indicator symbol, and may include, as another example, a shift position symbol, a warning symbol (a warning light also referred to as a telltale), and the like. In the second base light transmitting portion 84, a light reducing portion 88 for reducing light is formed on the image display surface 13c side of the second base light transmitting portion 84, that is, on the back side in the depth direction Y. The light reducing portion 88 is formed, for example, by printing a dark synthetic resin on the image display surface 13 c side of the second base light transmitting portion 84 by screen printing. The second base light transmitting portion 84 and the light reducing portion 88 constitute an indicator light transmitting layer R2 of the design plate 80. In the indicator transmission layer R2, each visible light source 50 is disposed on the back side in the depth direction Y. Indicator light transmission layer R2 can suppress that each visible light source 50 is visually recognized from visual observation position EP by light reduction part 88, and can improve designability. The indicator light transmission layer R2 transmits the visible light emitted from the visible light sources 50 and reduced by the light reduction portion 88 to the visual position EP side, and causes the design pattern 84a (for example, a direction indication symbol) to emit light.

  The light shielding portion 85 is a portion that shields light. The light shielding portion 85 is provided on the outside of the first base material transmitting portion 82, and is formed in a planar shape by a black light shielding printing layer which is the same as the light shielding printing layer of the gradation portion 83. The light shielding unit 85 is printed by, for example, inkjet printing or screen printing. The light shielding portion 85 is formed adjacent to the gradation portion 83 in a region outside the outer peripheral portion of the gradation portion 83. Specifically, the light shielding portion 85 forms the second boundary 85 a with the outer peripheral portion of the gradation portion 83, and the image display of the area excluding the second base material transmitting portion 84 and the base 81 outside the second boundary 85 a It is provided on the surface 13c side. The light shielding portion 85 shields the light incident from the front side and the rear side in the depth direction Y. The light shielding portion 85 constitutes a light shielding layer R3 of the design plate 80. The light shielding layer R3 shields light incident from the visual position EP side and shields light emitted to the visual position EP side.

  The overcoat portion 86 is a portion covering the surface of each dot 83 a of the gradation portion 83. The overcoat portion 86 is made of, for example, a synthetic resin having a lower electrical resistance than the dial plate 60 and the design plate 80, and is formed as a light-transmissive printable layer. The overcoat 86 is formed of, for example, a smoke material. The overcoat 86 covers the entire surface of each dot 83a by the transmissive printing layer. In the overcoat portion 86, for example, the transmissive printing layer fills the gaps between the adjacent dots 83a and covers the top of the projection direction (the depth direction Y) of the dots 83a. The overcoat portion 86 covers each dot 83a with a predetermined thickness on the image display surface 13c side in the projecting direction from the top of each dot 83a. In the present embodiment, the overcoat portion 86 is further provided over the entire area of the first substrate transmitting portion 82 on the image display surface 13 c side. That is, the overcoat part 86 is provided in the gradation part 83 and the first base material transmitting part 82. The overcoat portion 86 is printed, for example, from the gradation portion 83 to the first substrate transmitting portion 82 by inkjet printing, screen printing, or the like. The overcoat portion 86 is printed using, for example, a UV curing ink, a solvent or the like in order to obtain gloss, but is not limited thereto. Since the overcoat part 86 can be formed by printing, the manufacturing cost can be suppressed. The overcoat 86 has a refractive index that refracts light closer to the gradation portion 83 than air. With this configuration, the difference in refractive index between the gradation portion 83 and the overcoat portion 86 is smaller than the difference in refractive index between the conventional gradation portion and air. Thereby, the overcoat part 86 can suppress that light is scattered on the surface of each dot 83a of the gradation part 83, and can suppress that the gradation part 83 is observed white. The gradation portion 83 and the overcoat portion 86 constitute a gradation layer R4 of the design plate 80. The gradation layer R4 obscures the boundary between the display transmission layer R1 and the light shielding layer R3 as viewed from the visual position EP.

  The design plate 80 has a transmittance of about 25% to 75% for the display transmission layer R1 including the front glass 30, the anti-reflection processing part 87, the first base material transmission part 82, and the overcoat part 86.
