The light diffusing plate includes a light-transmissive support, a diffusing layer having light-transmissive spheres, and a light-sensitive color forming material interposed between the support and the diffusing layer, the light-sensitive color forming material containing a positive-acting diazo light- and heat-sensitive material or a positive-acting silver halide light-sensitive emulsion, or a negative-acting light-sensitive color forming material in the side contacting the light-transmissive spheres and a positive-acting light-sensitive color forming material in the side of the support, the light-sensitive color forming material being developed to take on color after generally parallel light is launched from a side where the diffusing layer is provided. The display apparatus makes use of the diffusing plate. |
