Abstract
The present invention has an object to provide a polymerizable liquid crystal compound used for formation of an optically anisotropic film having excellent reciprocal wavelength dispersion and moisture-heat resistance, a polymerizable liquid crystal composition, an optically anisotropic film, an optical film, a polarizing plate, and an image display device. The polymerizable liquid crystal compound of the present invention is a polymerizable liquid crystal compound represented by Formula (1), in which a Clog P value of a group represented by Ar in Formula (1) is 4.3 or more and less than 7.0.
