Patent ID: 8354494

Claim:
A polymerizable liquid crystal composition comprising at least one liquid crystal compound selected from compounds represented by Formula (1-1) and Formula (1-2) as a component (A), at least one liquid crystal compound selected from compounds represented by Formula (2) as a component (B), at least one liquid crystal compound selected from compounds represented by Formula (3) as a component (C), and at least one optically active compound selected from compounds represented by Formula (4) as a component (D), wherein a ratio of the component (A) is from 45 to 85% by weight, a ratio of the component (B) is from 10 to 30% by weight, a ratio of the component (C) is from 0 to 10% by weight, and a ratio of the component (D) is from 5 to 15% by weight, based on a total weight of the composition: wherein in Formula (1-1), R 1 and R 2 each independently represents hydrogen, methyl, ethyl, fluorine or chlorine; W 1 independently represents hydrogen or fluorine; and m1 independently represents an integer of from 1 to 10, in Formula (1-2), R 3 represents hydrogen, methyl, fluorine, chlorine, acetyl, acetoxy or methoxy; Y 1 independently represents —O— or a group represented by Formula (5); and m2 independently represents an integer of from 1 to 10: in Formula (2), R 4 represents cyano, fluorine, chlorine, —OCF 3 , alkyl having from 1 to 10 carbon atoms or alkoxy having from 1 to 10 carbon atoms; Y 2 represents a single bond, —O— or a group represented by Formula (5); Y 3 represents a single bond, —COO—, —OCO— or —C≡C—; W 2 represents hydrogen or fluorine; and m2 represents an integer of from 1 to 10, in Formula (3), Y 4 independently represents a single bond or —O—; and n independently represents an integer of from 0 to 10, and in Formula (4), R 5 independently represents methyl or ethyl; A l independently represents 1,4-phenylene or 4,4′-biphenylene; A 2 independently represents 1,4-phenylene or 4,4′-biphenylene; Y 5 independently represents —COO— or —OCO—; Q independently represents a single bond or oxyalkylene having from 1 to 10 carbon atoms; and p independently represents 0 or 1.
