Abstract
An object of the present invention is to provide a polymerizable liquid crystal composition used for formation of an optically anisotropic film having excellent moisture-heat resistance and an excellent surface condition, an optically anisotropic film, an optical film, a polarizing plate, and an image display device. The polymerizable liquid crystal composition of an embodiment of the present invention is a polymerizable liquid crystal composition containing a polymerizable liquid crystal compound and a compound represented by Formula (1): L1-SP1-(E3-A1)m-E1-G1-C(═O)—O—C(═O)-G2-E2-(A2-E4)n-SP2-L2, in which a content of the compound represented by Formula (1) is 0.01 to 5 parts by mass with respect to 100 parts by mass of the polymerizable liquid crystal compound.
