A polymerizable liquid crystal compound shown by the following formula (I), a polymerizable liquid crystal composition that includes the polymerizable liquid crystal compound and a chiral compound polymerizable with the polymerizable liquid crystal compound, a liquid crystalline polymer obtained by polymerizing the polymerizable liquid crystal compound or the polymerizable liquid crystal composition, and an optical anisotropic article that includes the liquid crystalline polymer. The polymerizable liquid crystal compound shows a liquid crystal phase over a wider temperature range, is chemically stable, can be inexpensively produced, and has a wide selective reflection wavelength band &Dgr;λ (i.e., a large value &Dgr;n). The polymerizable liquid crystal composition includes the polymerizable liquid crystal compound, the liquid crystalline polymer is obtained by polymerizing the polymerizable liquid crystal compound or the polymerizable liquid crystal composition, and the optical anisotropic article includes the liquid crystalline polymer. wherein Y1 to Y6 represent —O—, —O—C(═O)—, —C(═O)—O—, or the like, G1 and G2 represent divalent aliphatic groups having 1 to 20 carbon atoms, Z1 and Z2 represent an alkenyl group having 2 to 10 carbon atoms or the like, A1 and A2 represent divalent organic groups A having 1 to 30 carbon atoms, X1 to X8 represent a hydrogen atom or the like, and a and b represent 0 or 1. |
