Rear projection screen, optical component thereof, and method for manufacturing the optical component

摘要

A rear projection screen includes a first and second optical components. The second optical component includes a first surface on which a plurality of cylindrical convex portions are formed, and a second surface opposite to the first surface. In this case, a plurality of concave portions are formed on the second surface, and each concave portion is positioned respectively corresponding to the place between each cylindrical convex portion. A light absorbing material is applied to each concave portion. Furthermore, the invention also discloses an optical component and a method for manufacturing the optical component.
