Abstract
An object of the present invention is to provide a polymerizable liquid crystal compound having excellent solubility, which is used for the formation of an optically anisotropic film having excellent durability, a method for producing the same, 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 embodiment of the present invention is a polymerizable liquid crystal compound represented by Formula (1), L1-SP1-A1-D3-G1-D1-Ar-D2-G2-D4-A2-SP2-L2 . . . (1) in Formula (1), the ClogP value of the group represented by L1-SP1-A1-D3-G1-D1 and the ClogP value of the group represented by L2-SP2-A2-D4-G2-D2 are different from each other, and at least one of the ClogP values is 3.3 or more.
