Abstract

An information display portion indicates vehicular information relevant to a vehicle. A display plate being translucent is located on a viewing side relative to the information display portion. A reflective portion formed in the display plate is configured to be illuminated in a predetermined shape by light emitted from a light source unit. The reflective portion being illuminated is overlapped on the vehicular information indicated by the information display portion and viewable on the viewing side.

First claim

What is claimed is:

1. A vehicular display device comprising:
an information display portion configured to indicate vehicular information relevant to a vehicle;
a first light source unit; and
a first display plate being translucent and located on a viewing side relative to the information display portion, wherein
the first display plate has a first reflective portion configured to be illuminated in a first predetermined shape by light from the first light source unit, and
the first reflective portion being illuminated is overlapped on the vehicular information by the information display portion and viewable on the viewing side,
the first reflective portion includes a recessed portion which is configured to reflect light, which is emitted from the first light source unit and conducted from an end side of the first display plate through the first display plate, to the viewing side to be illuminated in the first predetermined shape.

2. The vehicular display device according to claim 1 , wherein
a the recessed portion is formed on a surface of the first display plate on a side of the information display portion,
the recessed portion becomes thinner to the viewing side, and
the first light source unit is located on the end side of the first display plate in a plate surface direction.

3. The vehicular display device according to claim 1 , wherein
the first predetermined shape of the first reflective portion is a shape of a scale for indicating the vehicular information.

4. The vehicular display device according to claim 1 , wherein
the first light source unit, the first display plate, and the first reflective portion form a first combination,
the vehicular display device further comprising:
a second light source unit, a second display plate, which has a second reflective portion, forming a second combination,
the second combination and the first combination are arranged in a direction from a side of the information display portion to the viewing side,
the second reflective portion is in a second predetermined shape, and
the first predetermined shape is different from the second predetermined shape.

5. A vehicular display device comprising:
a display plate including a pointer display portion configured to indicate vehicular information by using a pointer;
a light source unit;
an information display portion having a display surface configured to indicate an image of various vehicular information; and
a display plate being translucent and located on a viewing side relative to the display surface, wherein
the display plate has a reflective portion on a side, which corresponds to the display surface,
the reflective portion includes a recessed portion which is configured to reflect light, which is emitted from the light source unit and conducted from an end side of the display plate through the display plate, to the viewing side to be illuminated in a predetermined shape,
and
the reflective portion is overlapped on the image indicated on the display surface and is viewable on the viewing side when being illuminated.

6. The vehicular display device according to claim 5 wherein
the display plate has a region corresponding to the pointer display portion, and
the region has an opening through which the pointer is inserted.

7. The vehicular display device according to claim 5 , wherein
the recessed portion is recessed from a counter-viewing side of the display plate to the viewing side.

8. The vehicular display device according to claim 5 , further comprising:
a control unit configured to control activation and deactivation of the light source unit, wherein
the control unit is configured to activate the light source unit to illuminate the reflective portion and to deactivate the light source unit to dim the reflective portion.

9. The vehicular display device according to claim 5 , wherein
the reflective portion forms an ornamental portion of the image.

10. The vehicular display device according to claim 5 , wherein
the reflective portion is formed in the display plate at a position around the image, and
the reflective portion does not conceal information indicated by the image.

11. A vehicular display device comprising:
a display plate including a pointer display portion configured to indicate vehicular information by using a pointer;
a light source unit;
an information display portion having a display surface configured to indicate an image of various vehicular information; and
a display plate being translucent and located on a viewing side relative to the display surface, wherein
the display plate has a reflective portion on a side, which corresponds to the display surface,
the reflective portion is configured to be illuminated in a predetermined shape by light emitted from the light source unit,
the reflective portion is overlapped on the image indicated on the display surface and is viewable on the viewing side when being illuminated, and
the reflective portion, which is formed in the display plate, forms a graphic pattern exhibiting, in combination with the image, a meaning for a viewer.

12. The vehicular display device according to claim 5 , wherein
the reflective portion and characters in a character portion of the display plate form a combination in which the reflective portion is located between characters, which are adjacent to each other.

13. A vehicular display device comprising:
a display plate including a pointer display portion configured to indicate vehicular information by using a pointer;
a light source unit;
an information display portion having a display surface configured to indicate an image of various vehicular information; and
a display plate being translucent and located on a viewing side relative to the display surface, wherein
the display plate has a reflective portion on a side, which corresponds to the display surface,
the reflective portion is configured to be illuminated in a predetermined shape by light emitted from the light source unit,
the reflective portion is overlapped on the image indicated on the display surface and is viewable on the viewing side when being illuminated, and
the reflective portion and the image form a combination in which the reflective portion surrounds the image.

14. A vehicular display device comprising:
an information display portion having a display surface configured to indicate an image of vehicular information relevant to a vehicle;
a display plate being translucent, the display plate located on a viewing side relative to the display surface and distant from the display surface; and
a light source unit located on an end side of the display plate in a plate surface direction, wherein
the display plate has a reflective portion including a recessed portion,
the recessed portion is configured to reflect light, which is emitted from the light source unit and conducted from the end side of the display plate through the display plate, to the viewing side to be illuminated in a predetermined shape, and
the light reflected by the reflective portion to the viewing side is overlapped on the vehicular information indicated by the information display portion.

15. The vehicular display device according to claim 14 , wherein
the information display portion includes a liquid crystal panel.

16. The vehicular display device according to claim 14 , wherein
the reflective portion forms an ornamental portion of the image.

17. The vehicular display device according to claim 14 , wherein
the reflective portion is formed in the display plate at a position
