Abstract
A rear projection screen includes a transparent substrate, a light absorbing film and a first diffusion film in sequence from a projection side to a viewer side. The transparent substrate includes a first surface and a second surface opposite to each other, the first surface faces the projection side, the second surface faces the viewer side, and the first surface is disposed with a plurality of prism structures protruding toward the projection side. The transparent substrate is located between the light absorbing film and the prism structures. The light absorbing film includes a plurality of light absorbing structures arranged at intervals from each other, and the distribution density of the prism structures is greater than that of the light absorbing structures. The light absorbing film is located between the first diffusion film and the transparent substrate. The rear projection screen through the above-mentioned design has a good image display quality.
