A projection screen including a polarized-light selective reflection layer
having a cholesteric liquid crystalline structure that causes selective
diffuse-reflection of a specific polarized-light component, and a
substrate for supporting the polarized-light selective reflection layer.
The polarized-light selective reflection layer includes three partial
selective reflection layers, each of which contains molecules of a liquid
crystal made from an organic compound, forming an organic film as a
whole, and has a cholesteric liquid crystalline structure that causes
selective diffuse-reflection of a specific polarized-light component.
Each partial selective reflection layer of the polarized-light selective
reflection layer is ordered according to wavelength of the range of light
reflected. Beginning from the observation side, the order is as follows:
blue (B) color wave range, green (G) color wave range, and red (R) color
wave range.
