Abstract:
1. A liquid crystal composition comprising a compound selected from compounds represented by formula (1) as a component (A), an optically active compound selected from compounds represented by formula (2) as a component (B), and a mixture of at least one photopolymerization initiator and at least one photosensitizer as a component (C), and a ratio of the component (A) being from 77 to 98% by weight, a ratio of the component (B) being from 1 to 15% by weight, and a ratio of the component (C) being from 1 to 8% by weight, based on a total weight of the composition: wherein Z independently represents a single bond or alkylene having from 1 to 10 carbon atoms; Y 1 independently represents a single bond or —O—; R 1 represents methyl or ethyl; A 1 and A 1 each independently represents 1,4-phenylene or 4,4′-biphenylene; Y 2 represents —COO— or —OCO—; Q represents a single bond or oxyalkylene having from 1 to 10 carbon atoms; and p represents 0 or 1.
