Abstract

The polymerizable compound of the present invention is represented by general formula (1) below and can provide a composition that is polymerizable near ambient temperature and exists in a liquid crystal phase at low temperatures. The composition and a (co)polymer of the polymerizable compound of the present invention are liquid crystal substances useful as optically anisotropic materials. (In the formula, each of rings A1 to A3 represents a benzene ring, cyclohexane ring, etc.; each of X to Z represents a C1-8 alkyl or alkoxy group, C2-6 alkenyl group, halogen atom, cyano group, or CH2═CR3—COO—; each of R1 to R3 represents a hydrogen atom, methyl group, or halogen atom; each of L1 to L3 represents —CH2CH2COO—, —COO—, —OCO—, —CH2CH2—, —O(CH2)f— (herein, f=1-8), etc.; n represents 0 or 1; and a to c represent such numbers that the polymerizable compound has at least one or more of any of X, Y, and Z).
