Patent ID: 8257611

Claim:
A liquid crystal composition, comprising at least one of a compound represented by formula (1): wherein A 1 and A 2 each independently represent a group selected from the group consisting of —O—, —NR— (in which R represents a hydrogen atom or a substituent), —S—, and —CO—; Z forms a benzene ring with the C—C═C—C or C═C—C═C in the formula; R 1 , R 2 , and R 3 each independently represent a substituent; m represents an integer of 0 to 4; L 1 and L 2 each independently represent a single bond or a divalent linking group; X is selected from ═O, ═S, ═NR 4 , and C(R 5 )R 6 wherein R 4 , R 5 and R 6 each independently represent a substituent; and at least one of R, R 1 , R 2 , R 3 , and R 4 is substituted with a polymerizable group, wherein the content of a liquid crystal compound in the liquid crystal composition is at least 30 mass %.
