摘要： A projection screen includes a base sheet, a surface roughness structure, a reflective layer, and a light absorption layer. The base sheet has a first side and a second side opposite to the first side. A plurality of first surfaces and second surfaces are formed on the first side, each first surface faces an optical projection system, and each second surface is disposed between two adjacent first surfaces and forms an angle with respect to a neighboring first surface. The surface roughness structure is formed on at least the first surfaces and capable of diffusing a light beam to a limited extent. The reflective layer is formed on the surface roughness structure and capable of reflecting most of the light beam diffused by the surface roughness structure to a limited extent towards a limited viewing cone, and the light absorption layer is formed on the second surfaces.
