Abstract

The present invention provides a display device, including a display plate having a front surface and a back surface located on a side opposite to the front surface, a transparent material through which a light is transmissive being formed into the plate-like display plate; a printed member disposed on the back surface of the display plate so as to have a display portion formed therein, a first portion through which a light is transmissive and a second portion through which the light is non-transmissive being formed in the printed member by carrying out printing, the display portion being composed of at least one of a symbol, a character and a pattern by the first and second portions; and a radiating portion for radiating a light to the display portion from a portion on a side opposite to the display plate with respect to the printed member.

Claims

1. A display device, comprising:

a transparent display plate having a front surface and a back surface, the display plate including;

a pearl ink layer disposed on the back surface of the display plate, the pearl ink layer being semi-light-transmissive;

a masking layer disposed on a side of the pearl ink layer opposite the back surface of the display plate, the masking layer having a first portion that is not light-transmissive and a second portion that is light-transmissive; and

a smoke ink layer disposed on a side of the masking layer opposite the back surface of the display plate, the smoke ink layer being semi-transparent;

a substrate having one or more light-transmissive areas in a shape of a symbol, a character or a pattern;

an adhesive layer that adheres the substrate to the back surface of the display plate; and

a radiating portion, disposed on a side of the substrate opposite the adhesive layer, that radiates light towards the one or more light-transmissive areas of the substrate, wherein

the adhesive layer adheres the substrate to a surface of the smoke ink layer on a side opposite a surface of the smoke ink layer facing the masking layer and to the back surface of the display plate through the smoke ink layer.

2. The display device according to claim 1, wherein

the display plate further includes:

a hairline layer including an irregular shape expressing a hairline disposed on the back surface of the display plate, wherein

the pearl ink layer is disposed on the hairline layer, and

the pearl ink layer is disposed on the back surface of the display plate through the hairline layer.

3. The display device of claim 2, wherein the hairline layer increases the light-transmissivity of the display plate.

4. The display device according to claim 1, wherein the substrate includes a non-light-transmissive ink disposed on a transparent sheet.

5. The display device according to claim 1, wherein the substrate is plastic.

6. The display device according to claim 1, wherein the first portion of the masking layer surrounds the second portion of the masking layer.

7. The display device according to claim 1, wherein,

the first portion of the masking layer is formed from ink, and

the second portion of the masking layer is an opening in the masking layer where no ink is disposed.

8. A display device, comprising:

a transparent display plate having a front surface and a back surface, the display plate including;

a first smoke ink layer disposed on the back surface of the display plate, the first smoke ink layer being semi-transparent;

a masking layer disposed on a side of the first smoke ink layer opposite the back surface of the display plate, the masking layer having a first portion that is not light-transmissive and a second portion that is light-transmissive; and

a second smoke ink layer disposed on a side of the masking layer opposite the back surface of the display plate, the second smoke ink layer being semi-transparent;

a substrate having one or more light-transmissive areas in the shape of a symbol, a character or a pattern;

an adhesive layer that adheres the substrate to the back surface of the display plate; and

a radiating portion, disposed on a side of the substrate opposite the adhesive layer, that radiates light towards the one or more light-transmissive areas of the substrate, wherein

the adhesive layer adheres the substrate to a surface of the second smoke ink layer on a side opposite a surface of the second smoke ink layer facing the masking layer and to the back surface of the display plate through the second smoke ink layer.

9. The display device according to claim 8, wherein the substrate is plastic.

10. The display device according to claim 8, wherein the first portion of the masking layer surrounds the second portion of the masking layer.

11. The display device according to claim 8, wherein,

the first portion of the masking layer is formed from ink, and

the second portion of the masking layer is an opening in the masking layer where no ink is disposed.
