摘要

An optically anisotropic layer is formed by a liquid crystal compound represented by General Formula 1, in which the long axes of the molecules are oriented.;;wherein L1 and L2 independently represent a linking group having a carbonyl group; F1 and F2 independently represent an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, or a halogen atom; n and m independently represent an integer from 0 to 4; a and b independently represent an integer from 1 to 4; T1 and T2 independently represent a spacer portion including a straight chain or branched alkylene or alkylene oxide group having 2 to 20 carbon atoms; and Ar represents a divalent group having at least one aromatic ring selected from a group consisting of aromatic hydrocarbon rings and aromatic heterocycles, the number of Π electrons in the Ar group being 8 or greater.

1. An optically anisotropic layer, comprising a liquid crystal compound represented by General Formula 1 below, or is formed by curing a polymerizable composition containing a liquid crystal compound represented by General Formula 1 below, the long axes of the molecules of the liquid crystal compound of General Formula 1 being oriented. wherein each of L1 and L2 independently represents a linking group having a carbonyl group; each of F1 and F2 independently represents an alkyl group having a carbon number within a range from 1 to 4, an alkoxy group having a carbon number within a range from 1 to 4, or a halogen atom; each of n and m independently represents an integer within a range from 0 to 4; each of a and b independently represent an integer within a range from 1 to 4; each of T1 and T2 independently represents a spacer portion including a straight chain or branched alkylene or alkylene oxide group having a carbon number within a range from 2 to 20; and Ar represents a divalent group having at least one aromatic ring selected from a group consisting of aromatic hydrocarbon rings and aromatic heterocycles, the number of Π electrons contained in the Ar group being 8 or greater.
