Abstract
A rear projection screen includes a prism film, a first diffusion layer, a second diffusion layer and a light absorbing film sequentially disposed along a first direction. The prism film includes a first light-transmitting substrate and prism structures, wherein the prism structures are disposed on a surface of the first light-transmitting substrate away from the first diffusion layer. The prism structures receive an image beam and guide the image beam to be transmitted along the first direction. The first diffusion layer and the second diffusion layer have different refractive indexes. There are light-absorbing structures disposed in the light absorbing film, and the light-absorbing structures are arranged spaced apart from each other.
