    摘要: 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. 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 P1—S1—A1—D1—E1— [wherein P1 represents a polymerizable functional group; S1 represents —(CH2)w—, —O(CH2)w—, —(CH2)wO—, —(CH2)wC(═O)O—, —(CH2)wOC(═O)—, —C(═O)O(CH2)w— or —OC(═O)(CH2)w— (w: 1 to 20); A1 and E1 each represent a hydrocarbon ring or a hetero ring, although E1 is a ring incorporated within the liquid crystal backbone; and D1 represents —C(═O)—O—(CH2)m—O—, —O(CH2)m—O—C(═O)—, —O—C(═O)—(CH2)m—O—, or —O(CH2)m—C(═O)—O— (m: 1 to 15)].
