Abstract
A polymerizable liquid crystal composition having excellent solubility, used for formation of an optically anisotropic film having excellent durability. The polymerizable liquid crystal composition contains a polymerizable liquid crystal compound P1 represented by Formula (1): A-Ar-A, a polymerizable liquid crystal compound P2 represented by Formula (2): A-Ar-B, and a polymerizable liquid crystal compound P3 represented by Formula (3): B-Ar-B.In Formulae (1) and (2), A's represent predetermined side chains, all of which exhibit the same C log P value, and in Formulae (2) and (3), B's represent predetermined side chains, all of which exhibit the same C log P value. It should be noted that A and B represent side chains having C log P values different from each other, in which the C log P value of A is larger than the C log P value of B and the C log P value of at least one of A or B is 3.3 or more.
