A polymerizable liquid crystal compound represented by the formula (I): <CHEM> wherein P<1> and P<2> independently represent a polymerizable group; A<1>, A<2>, L<1> and L<2> independently represent a divalent linking group constituted by a single bond, an oxygen atom, a sulfur atom, a carbonyl group, a sulfonyl group, a substituted or unsubstituted imino group, or a combination thereof; S<1> and S<2> independently represent a divalent linking group; Cy<1> and Cy<2> independently represent a cyclic group having 5 to 14 carbon atoms; and each of n1 and n2 represents an integer, the sum of n1 and n2 being 0 to 2, has excellent anisotropy in a refractive index and a wide transparent region and is resistant to cis-trans-isomerization by ultraviolet radiation. This polymerizable liquid crystal compound is used for preparing a liquid crystal polymer, which is suitable for an optical retardation film, an optically anisotropic element, a nonlinear optical device and an electro-optical device. |
