<P>PROBLEM TO BE SOLVED: To provide a projection screen with increased contrast of a screen and increased gain by improving a reflective front projection screen. Ž<P>SOLUTION: The projection screen includes a reflective layer, a light absorption structure, a plurality of diffusion layers, and a lens structure layer. The light absorption structure is located above the reflective layer and has a plurality of through-holes, part of the reflective layer being exposed out of the plurality of through-holes. The plurality of diffusion layers having a first refractive index, respectively, is placed in the plurality of through-holes having an absorption structure, and contacts with the part of the reflective layer exposing out of the plurality of through-holes. The lens structure layer is placed above the plurality of diffusion layers and the light absorption structure, and the light incoming side of the lens structure includes a plurality of convex lenses. The plurality of convex lenses respectively corresponds to the plurality of diffusion layers. The lens structure layer has a second refractive index, which is smaller than the first refractive index.
