ABSTRACT:
A liquid crystal light modulation element is provided that includes a liquid crystal layer held between a pair of substrates. The liquid crystal layer includes a liquid crystal material that exhibits a cholesteric phase and has a plurality of domains. The liquid crystal layer includes regions where the helical axes of the liquid crystal molecules in a focal conic state extend in regular directions within a plane that is substantially parallel to the surface substrate.
