Polymerizable liquid crystal compound, liquid crystal composition and optical anisotropic material

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 R1 is a hydrogen atom or a methyl group, Cy is a trans-1,4-cyclohexylene group, X1 is a 1,4-phenylene group or a trans-1,4-cyclohexlyene group, and R2 is a C1-8 alkyl 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.
