Projected-image display member and projected-image display system

The present invention provides a projected-image display member and a projected-image display system that are free from a double image and have a high reflectance and a high transmittance, thereby allowing sharp images to be displayed. The projected-image display member includes a reflection layer and a λ/2 phase difference layer, and the reflection layer includes a cholesteric liquid crystal layer that exhibits selective reflection in the visible light region. The projected-image display system includes the projected-image display member, wherein the λ/2 phase difference layer is disposed on the incident light side relative to the reflection layer, and the incident light is p-polarized light that oscillates in a direction parallel to a plane of incidence.
