More Information
Summary:A rear projection screen for use in a rear projection image display device comprises one or more sheet members through which light is sequentially transmitted from the side of a plane of incidence of the screen, the last sheet member comprising a transparent material as a base thereof, and a light diffusing layer provided on the side of a plane of emergence of the base. A light diffuser having a refractive index different from that of the base may be dispersed in the base so as to contrive a greater viewing angle. Further, a transperent binder for supporting the light diffuser dispersed in the light diffusing layer or the light diffuser itself may be colored in order to obtain a further enhanced contrast.
