Rear projection screen

A rear projection screen for receiving an image beam, the rear projection screen comprising a prism film, a first diffusion layer, a second diffusion layer and a plurality of light absorbing structures sequentially arranged in a first direction, wherein,

• the prism film comprises a first light transmissive substrate and a plurality of prism structures, the first light transmissive substrate has a first surface away from the first diffusion layer, the prism structures are disposed on the first surface, and the prism structures receive the image beam and guide the image beam to be transmitted in the first direction;
• the first diffusion layer and the second diffusion layer have different refractive indices;
• and
• the light absorbing structures have a gap therebetween, the second diffusion layer has a second surface facing the light absorbing structures, an area occupied by an orthographic projection of the light absorbing structures on the second surface is A1, a total area of the second surface is A2, and 1≤(A2−A1)/A1≤5.
