Abstract

A compound represented by the formula (1) is provided. A polymerizable liquid crystal composition containing the compound can be controlled in birefringence and is excellent in stability of a liquid crystal phase. An anisotropic polymer excellent in uniformity of alignment is obtained by coating and polymerizing the composition on a supporting substrate. In the formula (1), at least one of Rrepresents a polymerizable group, A represents a ring group, Y and Z each represent a single bond or alkylene; in which —CH— in the alkylene may be replaced by another group, and m and n each represent an integer of from 0 to 5.
