Abstract
A side chain type polymer liquid crystalline compound with which a light absorption anisotropic film having a high alignment degree can be formed, which includes a liquid crystalline composition, a light absorption anisotropic film which is formed of the liquid crystalline composition, a laminate, and an image display device. A liquid crystalline composition contains a side chain type polymer liquid crystalline compound and a dichroic substance, the side chain type polymer liquid crystalline compound is a copolymer having repeating unitsand, the repeating unithas a mesogenic group and an electron-withdrawing group having a Hammett's substituent constant σp of greater than 0 at a terminal of the mesogenic group, and the repeating unithas a mesogenic group and a group having a Hammett's substituent constant σp of 0 or less at a terminal of the mesogenic group.
