Abstract
A subject is to provide a polymerizable liquid crystal composition from which an optically anisotropic substance having twist alignment that is excellent in chemical strength (chemical resistance) and has only a small amount of alignment defects can be obtained. A solution is a polymerizable liquid crystal composition containing an optically active compound having a binaphthol moiety, an achiral polymerizable liquid crystal compound and a photopolymerization initiator having oxime ester.
