A projection screen capable of sharply displaying an image even under
bright environmental light with high image visibility. A projection
screen has a polarized-light selective reflection layer with a
cholesteric liquid crystalline structure, capable of selectively
reflecting a specific polarized light component, and a substrate for
supporting the reflection layer. Of the light entering the reflection
layer from the viewer's side, the right-handed light in the selective
reflection wave range is reflected from the reflection layer as reflected
light. As a result of structural non-uniformity in the cholesteric liquid
crystalline structure, the light that is selectively reflected (reflected
light) is diffused.
