| 摘要 |
The present invention provides a member for projection image display, including a reflection layer and a retardation layer, wherein the reflection layer includes a cholesteric liquid crystal layer exhibiting selective reflection in a visible light region, the cholesteric liquid crystal layer is a layer formed from a liquid crystal composition containing a discotic liquid crystal compound, and a front phase difference of the retardation layer is in a range of 50 nm to 400 nm; and a projection image display system which includes the above member for projection image display, wherein the retardation layer is disposed on an incident light side relative to the reflection layer, and the incident light is p-polarized light that vibrates in a direction parallel to a plane of incidence, which is capable of displaying a clear image having high reflectance and high transmittance, without a problem of a double image. |
