PURPOSE: A polymerizable liquid crystal compound, a polymerizable liquid crystal composition, and a polymer thereof are provided to secure the alignment uniformity of an optically anisotropic object, and to improve the stability of a liquid-crystalline phase. CONSTITUTION: A polymerizable liquid crystal compound is marked with chemical formula 1. In the chemical formula 1, Ra is a polymerizable group. A is selected from the group consisting of 1,4-cyclohexylene, 1,4-cyclohexenylene, 1,4-phenylene, naphthalene-2,6-diyl, tetrahydronaphthalene-2,6-diyl, fluorene-2,7-diyl, and bicyclo[2.2.2]octane-1,4-diyl. Z is either a single bond or an alkylene group with 1~20 carbons.
