ABSTRACT:
A concave mirror which has rigidity higher than an aluminum foil mirror and is light-weight and low cost compared with a polished glass mirror is composed of at least one concave mirror unit of a synthetic resin material molded to a concave shape and an aluminum reflecting layer vapor deposited on a front or rear surface of the concave mirror unit. A low cost image display device capable of projecting an image onto the concave mirror without using any specially designed projection lens includes at least a projection type cathode ray tube having a flat or substantially flat phosphor surface panel and a transmission type screen and the concave mirror. A multi-screen system which includes a plurality of the image display devices juxtaposed to provide an increased horizontal view angle is provided. Further, a sensory integration system using the image display device is provided.
