Abstract:
1. A display apparatus comprising: a plurality of transparent plates which are disposed to be superimposed and which allow entered light to pass therethrough and allow the light to exit through an exiting surface; light sources provided for the respective transparent plates to irradiate light onto a side end surface of each of the transparent plates; a plurality of diffusion portions, each of which is formed on a surface of each of the transparent plates facing the exiting surface, and which diffuse light from the light sources such that a position of maximum luminance of light exiting from each of the transparent plates differs between the transparent plates; and a reflector between the transparent plates, the reflector reflecting light so that light from a corresponding one of the light sources which perform irradiation on their corresponding transparent plates does not leak into another transparent plate.
