Even if optical anisotropy Δn is high, a liquid crystal phase is exhibited at room temperature, crystals do not precipitate, solubility in organic solvents is excellent, coating properties and orientation are excellent, and transparency after polymerization is excellent. A polymerizable liquid crystal compound and a polymer or copolymer of the polymerizable liquid crystal compound are provided. A polymerizable liquid crystal compound represented by the following general formula (1). (Wherein R 1 and R 2 represent a hydrogen atom, a methyl group or a halogen atom, rings A to C represent a benzene ring, a naphthalene ring, etc., and at least one of rings A to C is a condensed ring; ~Z represents such an alkyl group having 1 to 6 carbon atoms, L 1 ~L 3 is -COO -, - OCO -, - O (CH 2) j - ( where j = 1 to 8) or the like represents, n represents 0 or 1, and a to c represent a number that the polymerizable liquid crystal compound has at least one of X, Y, and Z.)
