Abstract
Provided are a liquid-crystal compound and a liquid-crystal composition containing the compound, of which the advantages are that they show nematic hybrid orientation on a rubbed TAC substrate, they are polymerizable in open air and they readily give a polymer having a high degree of polymerization even when exposed to a relatively small total quantity of light. The films formed by photopolymerizing them keep nematic hybrid orientation. The compound is represented by formula (1): wherein Ris a hydrogen or an alkyl; Ris a hydrogen, —OCF, etc.; Ais a 1,4-phenylene, etc.; Aand Aare independently a 1,4-cyclohexylene, a 1,4-phenylene, etc.; Xis a single bond, —O—, etc.; Xand Xare independently a single bond, —COO—, —C≡C—, —CONH—, etc.; m is an integer of from 0 to 20; and n is 1 or 0.
