Disclosed is a polymerizable liquid crystal compound which has excellent durability against blue laser lights, small refractive index and small light absorption. Also disclosed are a liquid crystal composition containing such a compound and an optically anisotropic material using such a liquid crystal composition. The polymerizable liquid crystal compound is represented by the formula (1) below. In the formula (1), R1 represents a hydrogen atom or a methyl group; Cy represents a trans-1,4-cyclohexylene group; X1 represents a 1,4-phenylene group or a trans-1,4-cyclohexylene group; and R2 represents an alkyl group having 1-8 carbon atoms. In the 1,4-phenylene group and trans-1,4-cyclohexylene group, a hydrogen atom bonded to a carbon atom may be substituted by a fluorine atom, a chlorine atom or a methyl group. |
