Claims12
A liquid crystal composition comprising:
- a liquid crystal compound;
- a photo-alignment compound;
- and
- a polymer obtained by polymerizing a monomer having two or more radically polymerizable double bonds and one or more hydroxyl groups,
- wherein the photo-alignment compound is a photo-sensitive compound having a photo-reactive group which is subjected to at least one of dimerization or isomerization by the action of light, and
- the photo-reactive group has a skeleton of at least one type of derivative or compound selected from the group consisting of cinnamic acid derivations, courmarin derivatives, chalcone derivations, maleimide derivatives, azobenzene compounds, stilbene compounds and spiropyran compounds.
