Abstract
The present invention provides a polymerizable liquid crystal compound having an excellent durability against blue laser light and having a small refractive index and small light absorption, a liquid crystal composition containing the compound, and an optical anisotropic material using the liquid crystal composition. The polymerizable liquid crystal compound represented by the following formula (1), provided that Ris a hydrogen atom or a methyl group, Cy is a trans-1,4-cyclohexylene group, Xis a 1,4-phenylene group or a trans-1,4-cyclohexlyene group, and Ris a Calkyl group. The above 1,4-phenylene group and the trans-1,4-cyclohexylene group may be such that a hydrogen atom bonded to a carbon atom in each group may be substituted by a fluorine atom, a chlorine atom or a methyl group.
