<p>The present invention provides a polymerizable liquid crystal composition characterized in that a value Xa represented by formula (Ia): Xa = (a+0.19b) + 0.0215(c+0.19d) is adjusted to 825 or less, wherein a (ppm) represents the concentration of a 3- to 4-mer impurity each having a cyano group, b (ppm) represents the concentration of a dimer impurity having a cyano group, c (ppm) represents the concentration of a 3- to 4-mer impurity having no ciano group, and d (ppm) represents the concentration of a dimer impurity having no cyano group, among oligomer impurities in the polymerizable liquid crystal composition. According to this polymerizable liquid crystal composition, light scattering can be reduced and consequently depolarization can be inhibited. Therefore, an optically anisotropic body having good polarization control performance can be produced.</p> |
