Abstract:
A photoreactive liquid crystal composition containing (A) a photoreactive polymer liquid crystal which includes a photoreactive side chain in which at least one type of reaction selected from (A-1) photocrosslinking and (A-2) photoisomerization occurs, and (B) a low molecular weight liquid crystal. An optical element or display element is formed having a liquid crystal cell including the photoreactive liquid crystal composition.
