Abstract

A display device includes: a transparent plate-shaped substrate capable of blocking light transmission in its partial region; a planar light-emitting body disposed on a back surface side of the substrate; a light-shielding plate capable of blocking light transmission in its partial region and disposed between the substrate and the light-emitting body; and a design part displayed on the substrate, having a predetermined shape formed from a character or graphic. A first light-shielding region formed from a recess with a same shape as an outline of the design part, and a second light-shielding region having a shape enlarged outward from an outline of the recess by a first dimension are respectively provided on the back surface side of the substrate and a front or back surface side of the plate. First and second light-shielding layers blocking light from the light-emitting body are formed in the first and second light-shielding regions, respectively.

First claim

What is claimed is:

1. A display device comprising:
a transparent plate-shaped substrate that is capable of blocking transmission of light in a partial region of the plate-shaped substrate;
a planar light-emitting body that is disposed on a back surface side of the plate-shaped substrate;
a light-shielding plate that is disposed between the plate-shaped substrate and the planar light-emitting body and capable of blocking transmission of light in a partial region of the light-shielding plate; and
a design part that is displayed on the plate-shaped substrate and has a predetermined shape formed from a character or a graphic,
wherein a first light-shielding region is provided on the back surface side of the plate-shaped substrate, the first light-shielding region being formed from a recess having a same shape as an outline of the design part, and a second light-shielding region is provided on a front surface side or a back surface side of the light-shielding plate, the second light-shielding region having a shape that is enlarged outward from an outline of the recess by a first dimension, and
a first light-shielding layer blocking light from the planar light-emitting body is formed in the first light-shielding region, and a second light-shielding layer blocking light from the planar light-emitting body is formed in the second light-shielding region.

2. The display device according to claim 1 , wherein a third light-shielding region is provided on the front surface side or the back surface side of the light-shielding plate, the third light-shielding region having a shape that is contracted inward from the outline of the recess by a second dimension, and
a third light-shielding layer blocking light from the planar light-emitting body is formed in the third light-shielding region.

3. The display device according to claim 2 , wherein the second dimension is larger than an assembly tolerance generated when the plate-shaped substrate is assembled to the light-shielding plate, in a direction along a back surface of the plate-shaped substrate.

4. The display device according to claim 1 , wherein the first light-shielding layer is formed from a metal vapor-deposited film formed on an inner surface of the recess.

5. The display device according to claim 1 , wherein the second light-shielding layer is formed by laminating a surface color printed layer, a white printed layer, and a black printed layer from a front surface side to a back surface side of the second light-shielding layer.

6. The display device according to claim 1 , wherein the display device is provided on a step part at a lower edge of a door opening of a vehicle.

7. A display device comprising:
a transparent plate-shaped substrate that is capable of blocking transmission of light in a partial region of the plate-shaped substrate;
a planar light-emitting body that is disposed on a back surface side of the plate-shaped substrate; and
a design part that is displayed on the plate-shaped substrate and has a predetermined shape formed from a character or a graphic,
wherein a first light-shielding region and a second light-shielding region are provided on the back surface side of the plate-shaped substrate, the first light-shielding region being formed from a recess having a same shape as an outline of the design part, and the second light-shielding region surrounding a periphery of the recess via a gap of a first dimension, and
a first light-shielding layer blocking light from the planar light-emitting body is formed in the first light-shielding region, and a second light-shielding layer blocking light from the planar light-emitting body is formed in the second light-shielding region.

8. The display device according to claim 7 , wherein the first light-shielding layer is formed from a metal vapor-deposited film formed on an inner surface of the recess.

9. The display device according to claim 8 , wherein the first light-shielding layer further comprises a black printed layer laminated on a back surface side of the metal vapor-deposited film.
