ABSTRACT:
Device for displaying imagery three-dimensionally, which comprises a first image reproduction element having an image reproduction surface and a second image reproduction element having an image indication surface of reflective property. Those image reproduction and indication surfaces are in an opposedly facing relation with each other, such that an imagery reproduced and indicated on the image reproduction surface is reflected by the image indicating surface to form a reflected imagery which is viewed by the eyes of person as if it was a three-dimensional image. One or both of such image reproduction and indication surfaces may be curved to have convex and concave surface sides, wherein the concave surface side is formed to have diffuse reflective property. The convex surface sides respective of those two surfaces may be in an opposedly facing relation with each other. Preferably, such two surfaces may each be a screen of light-transmissive type.
