ABSTRACT:
A polarizer including a polarization grating comprising a polarization sensitive photo-alignment layer and a liquid crystal composition arranged on said photo-alignment layer. An alignment pattern, corresponding to the polarization pattern of a hologram, is recorded in the photo-alignment layer, and the liquid crystal composition is aligned on the photo-alignment layer.
