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.
