[PROBLEMS] To provide a polymer liquid crystal having a large refractive index anisotropy and a small temperature dependency, and a polymerizable liquid crystal composition therefor. The liquid crystal composition contains a non-crosslinkable monomer of the general formula 1 and a crosslinkable monomer of the general formula 2, and the amount of the crosslinkable monomer in the liquid crystal composition is more than 10 mol%. Polymerizable liquid crystal composition. (R 1 -R 3 : hydrogen, halogen, alkyl group, etc., X 1 , X 2 : A single bond, —COO—, —OCO— or —O— is represented by Y 1 , Y 2 : represents —CH 2 —, —OCH 2 CH 2 — or —CH 2 CH 2 O— Z 1 to Z 10 : a single bond or a linking group; E 1 to E 8 : a 1,4-phenylene group or a trans-1,4-cyclohexylene group, respectively. m: 1 to 12, n, r: 1 to 10 Represents p, q, s, t: 0 or 1. ) |
