Abstract:
A liquid crystal composition contains a side chain type polymer liquid crystalline compound which can form a light absorption anisotropic film having a high alignment degree and has excellent solubility in a general-purpose solvent, a light absorption anisotropic film obtained using the composition, a laminate, and an image display device. The composition includes: a side chain type polymer liquid crystalline compound; and a dichroic substance, in which the compound is a copolymer having a repeating unit (1) containing a mesogenic group with a molecular weight of greater than 280 and a repeating unit (2) with a molecular weight of 280 or less, a content of the repeating unit (2) is less than 14% by mass with respect to a total mass of the compound, and a content of the dichroic substance is greater than 2% by mass with respect to a total solid content of the composition.
