Abstract:
1. A polymerizable liquid crystal composition comprising at least one compound selected from the group of compounds represented by the formula (1-1) and the formula (1-2) as a first ingredient, at least one compound selected from the group of compounds represented by the formula (2-1) and the formula (2-2) as a second ingredient, and at least one compound selected from the group of compounds represented by the formula (3-1) as a third ingredient, in which Y 1 and Y 2 each represents independently a single bond, —(CH 2 ) 2 — or —CH═CH—, W 1 and W 2 each represents independently hydrogen or fluorine, m 1 , m 2 , n 1 , and n 2 each represents independently an integer of from 2 to 15 in the formula (1-1) and the formula (1-2); W 3 represents hydrogen or fluorine, W 4 and W 5 each represents independently hydrogen or methyl, W 6 represents hydrogen or methyl, X 1 is a group represented by —O— or the following formula (X 1 -2), and m 3 , m 4 , n 3 , and n 4 each represents independently an integer of from 2 to 15 in the formula (2-1) and the formula (2-2); and R 1 represents cyano, trifluoromethoxy, alkyl of 1 to 10 carbon atoms, or alkoxy of 1 to 10 carbon atoms, W 7 represents hydrogen or fluorine, X 2 represents a single bond, —COO—, or —OCO—, and m 5 represents an integer of from 2 to 15 in the formula (3-1).
