  When the above-described prior art device is applied to such a device, the area of the specific information display section (hereinafter referred to as the specific information area) is the same as other areas, regardless of whether or not the specific shift lever position is selected. Since it is illuminated with illumination light from the first light source, there is a problem that it is impossible to alert the driver that the specific information display unit is vehicle information related to a specific shift lever position.

  Therefore, a display method of switching display that illuminates the specific information area only when a specific shift lever position is selected among all areas can be considered, but a plurality of light guides corresponding to the specific information area and other areas can be considered. In addition to the need for members, it is necessary to provide a light shielding element that prevents illumination light leakage between the light guide members. In addition, when the light shielding element is configured to be a light shielding member such as a light shielding partition provided separately from the light guide member, the number of components is increased and the light shielding member is assembled with the interval between the light guide members between the light guide members. In order to secure the size that can be assembled, the interval becomes wide, and as a result, there is a possibility that a sense of unity between the display units and the specific information display unit cannot be obtained.

  The present invention has been made in consideration of such circumstances, and its purpose is to ensure a sense of unity among a plurality of display units, and to provide a plurality of display units having different display purposes according to each purpose. An object of the present invention is to provide a display device for a vehicle that displays the information.

And as a component of the said resin molding, it has the resin molding part concerning a shielding part, and the resin molding part concerning a light guide part. In order to give a stronger sense of unity between the specific area display part and the related area display part, the resin molded part related to the shielding part has been thinned when the interval between the specific area display part and the related area display part is reduced. As a result, there is a possibility that the resin molded part is transparent.

  However, in addition to the above configuration, since the shielding portion is configured to be one of the light-shielding resin molded portion and the dark color resin molded portion, the shielding portion has a light color such as white that may be transparent due to thinning. It is not composed of a light-colored resin molded portion colored in a system color tone.

  According to the second aspect of the present invention, it is possible to make the occupant who visually recognizes the specific area display unit and the related area display unit in the area display unit more strongly giving a sense of unity.

  The basic configuration of the shift lever position display device 1 has been described above. Hereinafter, a characteristic configuration of the shift lever position display device 1 will be described.

(Characteristic configuration)
The light guide plate 20 includes a light receiving portion 22 and a plate-like portion 21 (hereinafter referred to as a first light guide portion) as “first light receiving portions”, and a light receiving portion 32 and a plate-like portion 31 as “second light receiving portions”. (Hereinafter referred to as the second light guide body portion), the shielding portion 70 is integrally formed with the first light guide body portions 21 and 22 and the second light guide body portions 31 and 32. As shown in FIGS. 1 and 3, the shielding part 70 is formed so as to surround the related display part 6 along the extending direction of the plate-like parts 21 and 22.

  Since the shielding part 70 having such a configuration is formed of a dark-colored resin having a relatively high light-shielding property such as black, one of the first light guide parts 21 and 22 and the second light guide parts 31 and 32 is provided. It is possible to effectively suppress the light received from the light receiving part from being guided to the other light guide part different from the one light guide part.

  In addition, since the shielding part 70 is integrally formed with the first light guide parts 21 and 22 and the second light guide parts 31 and 32, the first light guide parts 21 and 22 and the second light guides are formed. The parts 31 and 32 and the shielding part 70 are formed by individual constituent members, and it is not necessary to assemble these constituent members. In other words, it is necessary to ensure that the interval between the first light guide body parts 21 and 22 and the second light guide body parts 31 and 32 is large enough to allow the light-shielding part 70 to be assembled between them. There is no.

  Therefore, it is possible to avoid an increase in the distance between the first light guide body parts 21 and 22 and the second light guide body parts 31 and 32. The specific area display unit 5b and the related area display unit 6b illuminated by the second light guide units 31 and 32 can be visually recognized with a sense of unity.

  As shown in FIGS. 1 and 2, between the specific area display unit 5 b illuminated by the first light guide units 21 and 22 and the related area display unit 6 b illuminated by the second light guide units 31 and 32. This is because by reducing the interval, the passenger can be visually recognized with a sense of unity.

  Further, the shielding part 70 is preferably formed of a light-shielding resin material (hereinafter referred to as a light-shielding resin molding part), but not limited to this, a light-transmissive or semi-light-transmissive resin material. It is preferable that it is formed with what has translucency (henceforth a dark color type resin molding part) by coloring this to dark color tone, such as black.

  According to this, the shielding unit 70 having such a configuration is not configured by a light-colored resin molded portion colored in a light-colored color tone such as white. In other words, for example, even if the interval between both the first light guide portions 21 and 22 and the second light guide portions 31 and 32 is reduced and the shielding portion 70 is thinned, like the light-colored resin molded portion. There is no risk of see-through. Therefore, in the shielding part 70, the shielding part 70 can be thinned without any problem. Therefore, the interval between the specific area display part 5b and the related area display part 6b can be reduced, so that the occupant feels unity. It is possible to visually recognize the image by giving it more strongly.

  As shown in FIG. 3, in the light guide plate 10, the plate-like portion 21 of the first light guide body portion 21, 22 has a surface layer portion facing the area display portions 2 b, 3 b, 4 b, 5 b. A diffusion portion 23 is provided in which fine irregularities are formed by embossing. Further, the plate-like portion 31 of the second light guide body portions 31 and 32 is provided with a diffusing portion 33 in which fine irregularities are formed in the surface layer portion of the portion facing the related area display portion 6b. Yes. The area display units 2b, 3b, 4b, and 5b and the related area display unit 6b to be illuminated can be uniformly illuminated by the fine unevenness of the diffusing units 23 and 33, and thus displayed with good-looking illumination. Can do it. In the above-described embossing process, fine irregularities are simultaneously resin-molded at the time of resin molding of the first light guide body parts 21 and 22 and the second light guide body parts 31 and 32.

  As described above, the first light guide portions 21 and 22 and the second light guide portions 31 and 32 of the light guide plate 10 are subjected to precision processing with fine unevenness at the time of resin molding. Depending on the method in which the portion 70 is integrally formed with the first light guide portions 21 and 22 and the second light guide portions 31 and 32, the fine uneven portions of the diffusion portion 33 formed on the surface layer portion are damaged by scratches or the like. There is a possibility. In some cases, if damage such as scratches may occur on the surfaces of the first light guide body parts 21 and 22 and the second light guide body parts 31 and 32, This may cause leakage of light to the outside or irregular reflection inside, and thus may reduce the appearance.

  On the other hand, when the integral molding is performed, the shielding portion 70 is molded first, and the formed shielding portion 70 is interposed between the first light guide body portions 21 and 22 and the second light guide body portions 31 and 32. It is preferable that both are formed so as to be sandwiched. That is, the shielding part 70 is resin-molded in the previous manufacturing process, and the first light guide parts 21 and 22 and the second light guide parts 31 and 32 are secondary resins using the resin-molded shielding part 70 as an insert part. It is molded. According to this, the possibility that the first light guide body parts 21 and 22 and the second light guide body parts 31 and 32 are damaged in the manufacturing process of integrally molding can be significantly reduced by forming in a subsequent process. Is possible.

  Further, when the shielding part 70 is inserted into the mold as an insert part during the secondary resin molding, the first light guide parts 21 and 22 and the second light guide parts 31 and 32 are formed in the shielding part 70. The resin molding pressure due to the molten resin will be received. It is preferable to increase the strength with respect to such a resin molding pressure as follows.

  That is, as a first method, as shown in FIG. 2, protrusions projecting from the first light guide body parts 21, 22 and the second light guide body parts 31, 32 on both ends of the shielding part 70. The parts 71 and 72 are provided. Thereby, since the physique of the shielding part 70 can be expanded in the direction of both ends, the strength of the shielding part 70 can be increased.

  First, in the light guide plate 10, part of the light traveling inside the first light guide parts 21, 22 to the area display parts 2 b, 3 b, 4 b, 5 b is emitted outside the first light guide parts 21, 22. Similarly, there is a possibility that part of the light traveling inside the second light guide portions 31 and 32 to the related area display portion 6b is emitted outside the second light guide portions 31 and 32. There is.

  In the case where there is a light shielding wall member 75 as shown in FIG. 2 ahead of the light emitted to the outside of the light guide body, there are the following concerns. That is, the light reflecting action at the light shielding wall member 75, for example, part of the light traveling inside the first light guide parts 21 and 22 to the area display parts 2b, 3b, 4b and 5b is reflected by the light. Therefore, there is a concern that there is a risk of being guided to the unintended second light guide portions 31 and 32. The light shielding wall member 75 is provided between the first light emitting diode 41 d and the fourth light emitting diode 51.

  As a countermeasure configuration, the shielding unit 70 has a convex portion 71 that protrudes toward the light shielding wall member 75 with respect to the first light guide body portions 21 and 22 and the second light guide body portions 31 and 32, and The light shielding wall member 75 is provided with a concave portion 76 that fits into the convex portion 71, and the convex portion 71 and the concave portion 76 form a fitting portion. Therefore, even if there is a light shielding wall member 75 ahead of the light emitted to the outside of the light guide body and light is generated by the reflection action of the light shielding wall member 75, the convex portion 71 and the concave portion 76 are provided. By the fitting portion configuration, the guiding to the second light guide portions 31 and 32 can be prevented.
