Abstract

Provided is a display device for which the display content is easily viewed. A display device comprises: a cover plate having a gauge section on which an index is represented and a light transmitting portion that transmits light from the back; a needle that rotates on the gauge section and points to the index; and a display that is disposed behind the light transmitting portion and shows an image via the light transmitting portion. When viewing the display device in planar view, the gauge section has an overlapping region that overlaps with a portion of a display section where the display emits light, and the cover plate adheres to the display by a transparent resin that is between the cover plate and the display and spans at least the region of the light transmitting portion.

First claim

The invention claimed is:

1. A display device, comprising:
a pointer;
a cover plate having a gauge section, on which an index pointed by the pointer is expressed, the gauge section configuring a pointer-type instrument together with the pointer and a light-transmitting portion that transmits light; and
a display, which is disposed behind the light-transmitting portion, and has a display region for display an image through the light-transmitting portion, wherein:
the gauge section has an overlapping region that laps over a part of the display region, when viewing in plan,
the light-transmitting portion and the display region of the display are in close contact through a transparent resin,
a light-shielding spacer different from the transparent resin lies between the overlapping region and the display region of the display, and
in a plan view, the light-shielding spacer which is formed of molding resin or metal has a shape of cutting out a part of a circle.

2. The display device according to claim 1 , wherein at least a part of the overlapping region has a light-shielding property.

3. The display device according to claim 1 , wherein:
the light-shielding spacer different from the transparent resin lies between the overlapping region and the display region of the display, and
the gauge section guides light incident from a side of the cover plate, and emits the light from a part of the gauge section.

4. The display device according to claim 3 , wherein:
the light-shielding spacer different from the transparent resin lies between the overlapping region and the display region of the display,
a light guide plate having a light-transmitting property is disposed between the gauge section and the spacer, and
light guided by the light guide plate exits from a part of the gauge section.

5. The display device according to claim 4 , wherein:
the gauge section has a ring portion that is formed three-dimensionally so as to surround the index,
the light guide plate is housed in a concave portion in the rear of the cover plate, which is generated by that the ring portion is formed.

6. The display device according to claim 5 , wherein a rear surface of the light guide plate is located in the forward of a rear surface of the light-transmitting portion of the cover plate, or in the same position as a rear surface of the light-transmitting portion.

7. The display device according to claim 1 , wherein:
the display region in the display is rectangular, and
the gauge section is substantially circular.
