Abstract:
A polymerizable liquid crystal compound is represented by the following formula (1): P-Sp1-L1-M1-L2-Sp2-Ox (1) wherein P represents a polymerizable group; one of Sp1 and Sp2 represents a branched alkylene group, or an alkylene group containing, in the chain thereof, at least one divalent linking group selected from the group consisting of —O—, —C≡C— and —S—; the other of Sp1 and Sp2 represents a straight chain alkylene group; each of L1 and L2 independently represents a divalent linking group; M1 represents a mesogenic group; and Ox represents a substituent containing an oxetanyl group.
