Provided is a polymerizable liquid crystal composition capable of obtaining an optically anisotropic body having reduced light scattering, depolarization suppression, and good polarization control performance. Among the oligomeric impurities in the polymerizable liquid crystal composition comprising the general formulas (a) and (b), the concentration of tri- to tetrameric impurities having a cyano group is a (ppm), and 2 having a cyano group. The concentration of the monomer impurity is b (ppm), the concentration of the tri to tetramer impurity not having a cyano group is c (ppm), and the concentration of the dimer impurity not having a cyano group is d (ppm). When the polymerization is characterized in that the Xa value represented by the formula (Ia), Xa = (a + 0.19b) +0.0215 (c + 0.19d) (Ia), is controlled to be 825 or less Liquid crystal composition.
