Abstract:
Due to the present invention, a reflection member including two or more layers of fixed cholesteric liquid crystal phases, in which the two or more layers of fixed cholesteric liquid crystal phases exhibit central wavelengths of mutually different selective reflection, and the two or more layers of fixed cholesteric liquid crystal phases include a layer formed of a composition including a disc-like liquid crystal compound and a layer formed of a composition including a rod-like liquid crystal compound and a projected image display member and a heat shield member which include the reflection member are provided. The reflection member of the present invention has favorable selective reflection characteristics with respect to oblique incidence rays.
