Abstract:
The present invention provides a liquid crystal composition with which a light absorption anisotropic film excellent in plane shape uniformity with a high alignment degree can be formed, a method of producing same, a light absorption anisotropic film, a laminate, and an image display device. The liquid crystal composition contains a high-molecular weight liquid crystal compound, and a dichroic substance, where the composition is a copolymer containing 90% by mass or more of a repeating unit (1) of Formula (1) and 10% by mass or less of a repeating unit (2) of Formula (2). In Formulae (1) and (2), P1 to P3 represent main chains, L1 to L3 represent a single bond or divalent linking group, P2 to SP3 represent a single bond or spacer group (SP1), M1 to M3 represent mesogenic groups, T1 represents a terminal group, and n and m are integers of 0 or 1.
