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[wherein P<1 >represents a polymerizable functional group; S<1 >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); 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-(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)].
