Abstract
A reflection screen includes a light-reflecting substrate laminated with a light-transmitting polymer layer having light absorptive crazes of regular directionality. The reflection screen is formed by coating or laminating the light-reflecting layer on the substrate, drawing over a blade in a direction perpendicular to the blade to form the crazes and inserting a light-absorbing material into the crazes. Images projected on the reflection screen have high contrast and can be observed as sharp images even in a lighted area such as in a room lighted by fluorescent lighting.
