    摘要: A polymerizable liquid-crystal composition containing a polymerizable liquid-crystalline compound, which shows a nematic phase at low temperatures, has excellent compatibility with other polymerizable liquid-crystalline compounds to be used in combination therewith, and gives through polymerization a polymer excellent in transparency and mechanical strength. The polymerizable composition shows a liquid-crystal phase and contains a compound (I) having a liquid-crytalline skeleton with two or more rings and a segment structure represented by the general formula P -S -A -D -E - [wherein P is a polymerizable functional group; S is -(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 is 1 to 20); A and E each is a hydrocarbon ring or heterocycle or E is one of the rings contained in the liquid-crystalline skeleton; and D is -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 is 1 to 15)].
