A transmission type screen 362 includes: two light diffusion plates 363a and 363b that respectively have flat surfaces 368a and 368b and light diffusion surfaces 367a and 367b that face the flat surfaces 368a and 368b, respectively, and diffuse and transmit incident light. The two light diffusion plates 363a and 363b are layered such that the respective light diffusion surfaces 367a and 367b face each other, and the respective light diffusion surfaces 367a and 367b diffuse light that is incident on the light diffusion surfaces 367a and 367b in substantially the same light distribution. The light diffusion plates 363a and 363b respectively include base members 366a and 366b having respective principal surfaces and a plurality of light diffusion members 369a and a plurality of light diffusion members 369b that are provided on the respective principal surfaces, and the light diffusion surfaces 367a and 367b may be formed of the respective principal surfaces on which the light diffusion members 369a and the light diffusion members 369b are provided.
