Title: TRANSPARENT SCREEN AND IMAGE PROJECTION SYSTEM
Abstract:
The purpose of the present invention is to provide: a transparent screen having good diffuse reflectivity and excellent transparency with low haze; and an image projection system. The present invention includes a supporting body, and a plurality of cholesteric liquid crystal layers laminated on the supporting body and formed by fixing the cholesteric liquid crystal phase. Among the plurality of cholesteric liquid crystal layers, at least one of the layers is a wave-type cholesteric liquid crystal layer where a bright part and a dark part deriving from the cholesteric liquid crystal phase have a wave-shaped structure in a cross section. Among the plurality of cholesteric liquid crystal layers, at least one other layer is a flat-type cholesteric liquid crystal layer where a bright part and a dark part deriving from the cholesteric liquid crystal phase has a flat structure parallel to the main surface of the supporting body in a cross section.
