Abstract:
A polymerizable liquid crystal composition is provided that is excellent in UV curing characteristics in the air and is excellent in orientation homogeneity, and a polymer film as a selective reflection film is provided that is obtained by orienting and polymerizing the composition on a supporting substrate. The liquid crystal composition contains a compound (1), a compound (2), a compound (3), a compound selected from a group of compounds represented by the formulae (4) to (6), and a surfactant. In the following formulae Y1 to Y4 and Y6 are each alkylene, A2, A3, A41, A42, A51, A52 and A6 are each a cyclic group, Z2 to Z4 and Z6 are each a bonding group, P4 and P6 are each an integer of from 0 to 3, R2, R31 and R32 are each hydrogen, halogen or alkyl, and Q1 and Q2 are each a polymerizable group.
