An object of the present invention is to provide a polymerizable liquid crystal composition incorporating a polymerizable liquid crystal compound which displays a low nematic phase temperature, displays excellent compatibility with other polymerizable liquid crystal compounds, and furthermore yields a product following polymerization, of good transparency and high mechanical strength. n A polymerizable composition is provided which displays a liquid crystal phase, and moreover incorporates a liquid crystal backbone with two or more ring structures and a compound with a partial structure represented by the general formula n P 1 —S 1 —A 1 —D 1 —E 1 — n [wherein P 1 represents a polymerizable functional group; S 1 represents —(CH 2 ) w —, —O(CH 2 ) w —, —(CH 2 ) w O—, —(CH 2 ) w C(═O)O—, —(CH 2 ) w OC(═O)—, —C(═O)O(CH 2 ) w — or —OC(═O)(CH 2 ) w — (w: 1 to 20); A 1 and E 1 each represent a hydrocarbon ring or a hetero ring, although E 1 is a ring incorporated within the liquid crystal backbone; and D 1 represents —C(═O)—O—(CH 2 ) m —O—, —O(CH 2 ) m —O—C(═O)—, —O—C(═O)—(CH 2 ) m —O—, or —O(CH 2 ) m —C(═O)—O— (m: 1 to 15)]. |
