The present invention provides a member for displaying a projected image and a projected image display system in which a clear image can be displayed with high reflectivity and high transmittance without a double image, the member for displaying a projected image including a reflection layer, and a λ/2 phase difference layer, in which the reflection layer includes a cholesteric liquid crystal layer having selective reflection in a visible light range, and the projected image display system including the member for displaying a projected image, in which the λ/2 phase difference layer is disposed on an incidence ray side with respect to the reflection layer, and the incidence ray is p-polarized light which vibrates in a direction parallel to an incidence surface.
