  In the display plate 11, the front surface of the display plate 11 is given gloss because the printing layer 22 has gloss. The printing layer 22 has a metallic color to which metallic gloss is given, and forms a metallic layer. Further, the printed layer 22 has light reflectivity due to the fact that metal powder such as aluminum powder is contained in the paint or ink, and the light reflectivity varies depending on the content of the metal powder. ing.

  The light reflectance is set uniformly for each of the meter region 42, the decoration region 44, and the outer peripheral region 45. On the other hand, the reflectance of the decoration region 44 is set higher than the reflectances of the meter region 42 and the outer peripheral region 45.

Specifically, in the decoration region 44, the light transmittance at the boundary between the intermediate region 41 and the meter region 42 is the smallest, and this light transmittance is substantially the same as these regions 41 and 42.

  In the meter region 42 and the outer peripheral region 45, the printing layer 22 is formed by performing printing so that the saturation and the brightness are uniform. On the other hand, in the decoration area 44, the print layer 22 is formed by gradation printing so that the saturation and lightness gradually increase as the color approaches the outer peripheral area 45.

  In addition, about the display board 11, the curved shape of the decoration area | region 44 is formed by performing the air-pressure shaping | molding of the base material in the state which printed on the flat base material. The meter area 42 corresponds to the display base portion, and the decoration area 44 corresponds to the display extension portion. The print layer 22 corresponds to both a hairline layer and a metallic layer.

The light guide plate 56 is disposed at the front position on the rear side surface portion 12b of the case 12, and is fixed to the case 12 while being pressed against the front end portion of the rear side surface portion 12b.

  In the light guide plate 56, when the light of the light emitting unit 55 is incident from the rear surface, the entire front surface of the light guide plate 56 emits light with substantially the same brightness as the light travels inside. In this case, almost the entire meter area 42 is uniformly illuminated from behind by the light of the light emitting unit 55. The light guide plate 56 is superimposed on the rear surface of the meter region 42, while being spaced rearward from the decoration region 44. The distance of the light guide plate 56 from the decorating region 44 increases as the portion is closer to the outer peripheral region 45.

  When the light emitting unit 55 emits light, the entity-side indicator 47a is displayed by emitting the light forward. On the other hand, the liquid crystal side index 47b emits light by light emitted from the liquid crystal panel 35 along with image display. In this case, on the liquid crystal panel 35, an image that emits substantially the same luminance and color as the light from the light guide plate 56 is displayed at the rear position of the liquid crystal side index 47b.

  In the decoration area 44, the luminance of light emission accompanying the incidence of light from the light emitting unit 55 gradually increases as it approaches the outer peripheral area 45, and gradation is given to the decoration area 44 by this light. Become.

  As described above, the light guide plate 56 is spaced downward from the decorating region 44, but the light from the light guide plate 56 reaches the decorating region 44 without its brightness being extremely reduced. ing. For this reason, in the whole decoration area | region 44, the brightness | luminance by the light from the light-guide plate 56 is ensured appropriately. In this case, the manufacturing cost of the light guide plate 56 can be reduced as compared with the configuration in which the light guide plate 56 has a special shape in accordance with the shapes of the decoration region 44 and the outer peripheral region 45.

  The vehicle display device 10 includes a decorative ring portion 61 that extends along the peripheral edge of the meter region 42. The decoration ring portion 61 is provided for each of the meters 31 and 32 and is superimposed on the front surface 42 a of the meter region 42. In this case, the decoration ring part 61 is in a state of being spanned between the substance area part 42b and the liquid crystal area part 42c of the meter area 42, and the part on the liquid crystal region part 42c side in the decoration ring part 61 is a liquid crystal. It is arranged at the front position of the panel 35.

  The decoration ring part 61 is formed of a light guide. The outer peripheral surface of the decorative ring portion 61 is formed by a plating layer deposited by plating, and this plating layer has a silver color. The plated layer has translucency and allows light to enter and exit the interior of the decorative ring portion 61. In addition, the decoration ring part 61 is equivalent to a light emission part.

  The decorative ring portion 61 is a circular annular member centered on the center line O. In the decorative ring portion 61, the radius of the inner peripheral end thereof is larger than the length dimension from the center line O in the pointer 48, and the radius of the outer peripheral end is the same as the radius of the meter region 42. Yes. In this case, it can be said that the decoration ring portion 61 has a shape extending along the movement locus N of the tip portion of the pointer 48.

  The decoration ring part 61 is installed in the state which protruded ahead from the meter area | region 42 by being overlaid on the front surface 42a of the meter area | region 42. FIG. Here, the pointer 48 includes a pointer boss 48a to which the pointer shaft portion 53 is fixed, and a long needle portion 48b extending from the pointer boss 48a. The pointer boss 48a is a flat cylindrical member, and the needle portion 48b extends from the peripheral surface portion of the pointer boss 48a toward the side. In this case, the projecting dimension of the decorative ring portion 61 from the meter area 42 is smaller than the projecting dimension of the pointer boss 48a from the meter area 42, and is the same as the projecting dimension of the tip of the needle part 48b from the meter area 42. It has become. That is, the decoration ring part 61 does not protrude forward from the tip part of the needle part 48b. In this case, it can suppress that the decoration ring part 61 becomes an obstruction and the visibility of the front-end | tip part of the needle part 48b falls.

  As shown in FIG. 3, the vehicle display device 10 includes a support bar 62 that supports the decorative ring portion 61, and a fixing member 63 that fixes the support bar 62 to the display plate 11. The support bar 62 and the fixing member 63 are both formed of a light-transmitting synthetic resin material. The support bar 62 extends rearward from the rear surface of the decorative ring portion 61, and includes the meter region 42 and the light guide plate. 56 penetrates through holes 65 provided in each of 56 and protrudes backward. A fixing member 63 is attached to the protruding portion, and the fixing member 63 has a size and shape that does not pass through the through hole 65, so that it is caught on the rear surface of the light guide plate 56. Yes.

  A plurality of the support rods 62 and the fixing members 63 are arranged at predetermined intervals along the decorative ring portion 61. The support rod 62 corresponds to a support portion, and the fixing member 63 corresponds to a hook portion.

  The meter region 42 is provided with a ring translucent portion 67 that transmits light from the light guide plate 56 and the liquid crystal panel 35 toward the decorative ring portion 61. The translucent portion 67 for the ring is a non-installation portion where the print layer 22 is not provided in the meter region 42, and is disposed at the rear position of the decorative ring portion 61. The ring translucent portion 67 extends along the decorative ring portion 61 and has a circular ring shape that is the same as the shape and size of the bottom surface of the decorative ring portion 61. In this case, light from the light guide plate 56 and the liquid crystal panel 35 is incident on the entire rear surface of the decorative ring portion 61. The ring translucent portion 67 may be formed not by a non-installed portion of the print layer 22 but by a portion where the translucency of the print layer 22 is increased.

  The decorative ring portion 61 is formed in a substantially rectangular shape in cross section. The decorative ring portion 61 includes an outer peripheral surface 61a facing the decorative region 44 side, an inner peripheral surface 61b facing the pointer 48 side, a front surface 61c facing front, and a chamfered surface 61d facing diagonally forward.

  When light from at least one of the light emitting unit 55 and the liquid crystal panel 35 is incident on the rear surface of the decorative ring portion 61 through the ring translucent portion 67, the incident light passes through the interior of the decorative ring portion 61. By proceeding, the entire outer peripheral surface 61a, inner peripheral surface 61b, front surface 61c and chamfered surface 61d emit light with substantially the same brightness. The light emitted from the decoration ring portion 61 illuminates the meter area 42 and the decoration area 44. In particular, the decoration area 44 is caused by the light emitted from the outer peripheral surface 61a and the chamfered surface 61d on the outer peripheral side. It will be brightly illuminated.

  The operational effects of the first embodiment described so far will be described below.

  According to the first embodiment, the decoration area 44 extends obliquely forward from the peripheral edge of the intermediate area 41 and the meter area 42 toward the outer peripheral side. Structure is given. And since the decoration area | region 44 has reflectivity, when the decoration ring part 61 light-emits, it reflects in the decoration area 44 with the light which reaches a user directly from the decoration ring part 61, and The appearance of the vehicular display device 10 can be enhanced by both the light reaching the user and the light reaching the user. Furthermore, since the reflectance of the meter area 42 is smaller than that of the decoration area 44, the brightness of the decoration ring portion 61 is easily distinguished by the presence of the meter area 42. Therefore, it is possible to create a three-dimensional effect as if the decorative ring portion 61 is raised forward from the meter region 42.

  According to the first embodiment, since the hairline pattern is given to the inner peripheral surface 44a of the decoration region 44, the appearance of the display board 11 can be enhanced by this hairline pattern. In addition, in the hairline pattern, since many lines are arranged in the depth direction of the display device 10 for the vehicle, the hairline pattern can create a sense of depth and a three-dimensional appearance that are greater than the dimension extending forward of the decoration region 44. it can.

  According to the first embodiment, since the metallic color is given to the inner peripheral surface 44a of the decoration region 44, the appearance of the display board 11 can be enhanced by this metallic color. Further, in this case, since the inner peripheral surface 44a is provided with reflectivity by a metallic color, the light that reaches the user after being reflected by the decoration region 44 in a state where the decoration ring portion 61 emits light. Brightness can be secured appropriately. Moreover, since the hairline pattern is expressed by a metallic color in the printing layer 22, the manufacturing cost of the display board 11 can be reduced as compared with the configuration in which the hairline pattern and the metallic color are separately provided to the display board 11. Can be reduced.

  According to the first embodiment, since the transmissivity of the decoration area 44 gradually increases as it approaches the outer peripheral area 45, when the light emitting unit 55 emits light, a gradation due to light is applied to the decoration area 44. Can be granted. In this case, it is possible to make the depth feeling and the three-dimensional feeling more than the dimension extending forward of the decoration region 44 remarkable by the gradation of light. In addition, since light reflectivity is provided with respect to the inner peripheral surface 44a of the decoration area | region 44, even if the brightness | luminance by translucency is low to some extent in the decoration area | region 44, a big problem does not arise regarding an appearance improvement. For this reason, since it is not necessary to make the light guide plate 56 overlap with the rear surface of the decoration region 44, a low-priced version can be realized as much as a flat light guide can be used as the light guide plate 56.

  According to the first embodiment, since the decorative ring portion 61 extends along the inner peripheral end of the decorative region 44, the light of the decorative ring portion 61 is reflected on the inner peripheral surface 44 a of the decorative region 44. It is easy to hit a wide area. In this case, since much light will be reflected in the decoration area | region 44, the improvement effect of the appearance by the reflected light can be heightened.

  According to the first embodiment, since the outer peripheral surface 61 a of the decorative ring portion 61 faces the inner peripheral surface 44 a of the decorative region 44, the light emitted from the outer peripheral surface 61 a is transmitted in the decorative region 44. The reflection efficiency can be increased. Moreover, since the outer peripheral surface 61a of the decorative ring portion 61 is orthogonal to the front surface 42a of the meter region 42, the inner peripheral surface 44a of the decorative region 44 extends to the outer peripheral side, so that the decorative region The structure which the light of the decoration ring part 61 reflected in 44 is easy to be discharge | released ahead is realizable.

  According to the first embodiment, in the vehicular display device 10 to which a three-dimensional feeling is given such that the decorative ring portion 61 is raised forward from the meter region 42, the decorative ring portion 61 is provided at the tip of the pointer 48. It extends along the movement locus N. For this reason, by making the decorative ring portion 61 conspicuous, it is possible to realize a configuration in which the consciousness of the user such as the driver easily shifts to the pointer 48.
