    摘要: To provide a transmission screen to be used for a PTV, particularly a high rigidity transmission screen suitably used for a high precision PTV on which an optical engine such as MD is mounted, capable of coping with enlargement of the screen, and a diffusion plate to be used therefor. A light diffusion plate comprising a substrate and a light diffusion layer formed on the substrate, wherein the light diffusion layer comprises at least two layers of a first light diffusion layer containing a first matrix and a first light diffusion agent having a refractive index difference Δn1 of 0.04≦Δn1≦0.2 with the first matrix, and a second light diffusion layer containing a second matrix and a second light diffusion agent having a refractive index difference Δn2 of 0.005≦Δn2≦0.04 with the second matrix; the volume fraction of the first light diffusion agent in the first light diffusion layer is less than 40%, and the volume fraction of the second light diffusion agent in the second light diffusion layer is at least 40%; and the total thickness of the light diffusion layers is from 5 to 200 μm by the thickness after curing.
