Abstract

The three dimensional display of the invention includes a display plate and a light source provided behind the plate. The display plate fundamentally includes a substrate made of a transparent material, an undercoating of transparent organic based color or colorless paint provided on the front surface of the plate, a light-reflective transparent metal coating on the undercoating, a transparent protective coating on the metal coating and a light-reflective surface provided on the rear surface of the substrate, the light reflective surface being opaque as a whole and including light-penetrable or transparent portions or vacant portions in the form of a predetermined image. To make the front surface of the display plate look like a roughened metal wall surface, the front surface of the substrate is roughened or the undercoating contains an agent which makes the front surface of the undercoating rough. To make the front surface of the display plate look like a blurred metal wall surface, the protective coating contains a deglazing agent.

Claims

1. A display for displaying an image in three dimensions, the display including:

a plate made of a transparent material;

an undercoating of transparent organic based paint provided on the front surface of the plate;

a light-reflective transparent metal coating on said undercoating;

a transparent protective coating on said metal coating, said protective coating containing a flatting or deglazing agent;

an opaque light-reflective coating on the rear surface of the plate, said opaque light-reflective coating including a vacant portion in the form of a predetermined image; and

a dark color light absorbing layer provided on the rear surface of said opaque light-reflective coating.

2. The display as set forth in claim 1 wherein said transparent organic based paint has a predetermined color.

3. A display for displaying an image in three dimensions, the display including:

a plate made of a transparent material;

an undercoating of transparent organic based paint provided on the front surface of the plate;

a light-reflective transparent metal coating on said undercoating;

a transparent protective coating on said metal coating, said protective coating containing a flatting or deglazing agent;

a light-reflective transparent coating provided on the rear surface of the plate; and

an opaque coating provided on the rear surface of the light-reflective transparent coating, a part of the opaque coating being removed in the form of a predetermined image.

4. The display as set forth in claim 3 wherein said transparent organic based paint has a predetermined color.

5. The display as set forth in claim 3 wherein a dark color light absorbing layer is provided on the opaque coating, a part of the light absorbing layer being removed in alignment with said removed part in said opaque coating.

6. The display as set forth in claim 3 wherein said opaque coating is made of a dark colored material.

7. A display for displaying an image in three dimensions, the display including:

a plate made of a transparent material;

an undercoating of transparent organic based paint provided on the front surface of the plate, the paint including an agent for roughening the front surface of the undercoating;

a light-reflective transparent metal coating on the undercoating;

a transparent protective coating on said metal coating;

an opaque light-reflective coating on the rear surface of the plate, said opaque light-reflective coating including a vacant portion in the form of a predetermined image; and

a dark color light absorbing layer provided on the rear surface of said opaque light-reflective coating.

8. The display as set forth in claim 7 wherein said transparent organic based paint has a predetermined color.

9. A display for displaying an image in three dimensions, the display including:

a plate made of a transparent material;

an undercoating of transparent organic based paint provided on the front surface of the plate, the paint including an agent for roughening the front surface of the undercoating;

a light-reflective transparent metal coating on the undercoating;

a transparent protective coating on said metal coating;

a light-reflective transparent coating provided on the rear surface of the plate; and

an opaque coating provided on the rear surface of the light-reflective transparent coating, a part of the opaque coating being removed in the form of desired image.

10. The display as set forth in claim 9 wherein said transparent organic based paint has a predetermined color.

11. The display as set forth in claim 9 wherein a dark color light absorbing layer is provided on the opaque coating, a part of the light absorbing layer being removed in alignment with said removed part in said opaque coating.

12. The display as set forth in claim 9 wherein said opaque coating is made of a dark colored material.

13. A display for displaying an image in three dimensions, the display including:

a plate made of a transparent material, the front surface of which is roughened so as to comprise convex portions, the convex portions of the roughened front surface being 25 microns or less;

an undercoating of transparent organic based paint provided on the front surface of the plate;

a light-reflective transparent metal coating on said undercoating;

a transparent protective coating on said metal coating;

an opaque light-reflective coating provided on the rear surface of the plate, said opaque light-reflective coating including vacant portions in the form of a predetermined image; and

a dark color light absorbing layer provided on the rear surface of said opaque light-reflective coating.

14. The display as set forth in claim 13 wherein said transparent organic based paint has a predetermined color.

15. A display for displaying an image in three dimensions, the display including:

a plate made of a transparent material, the front surface of which is roughened so as to comprise convex portions, the convex portions of the roughened front surface being 25 microns or less;

an undercoating of transparent organic based paint provided on the front surface of the plate;

a light-reflective transparent metal coating on said undercoating;

a transparent protective coating on said metal coating;

a light-reflective transparent coating provided on the rear surface of the plate; and

an opaque coating provided on the rear surface of the light-reflective transparent coating, a part of the opaque coating being removed in the form of a desired image.

16. The display as set forth in claim 15 wherein said transparent organic based paint has a predetermined color.

17. The display as set forth in claim 15 wherein a dark color light absorbing layer is provided on the opaque coating, a part of the light absorbing layer being removed in alignment with said removed part in said opaque coating.

18. The display as set forth in claim 15 wherein said opaque coating is made of a dark colored material.
