The invention provides a liquid crystal composite for an active-matrix-addressed electro-optical display device and application of the liquid crystal composite. The liquid crystal compound comprises a compound with a general formula (I) which occupies 10 percent to 30 percent of the total weight of the liquid crystal composite, a compound with a general formula (II) which occupies 5 percent to 30 percent of the total weight of the liquid crystal composite, a compound with a general formula (III) which occupies 10 percent to 40 percent of the total weight of the liquid crystal composite, and a compound with a general formula (IV) which occupies 10 percent to 60 percent of the total weight of the liquid crystal composite. The liquid crystal composite provided by the invention has a relatively high response speed and good low temperature storage stability. The invention further provides the active-matrix-addressed electro-optical display device comprising the liquid crystal composite.

Disclosed is a liquid crystal composition. The liquid crystal composition includes liquid crystal molecules including at least one of a liquid crystal compound having an alkenyl group and a liquid crystal compound having an alkoxy group, and a first stabilizer including a compound having a structure represented by Formula 1:where n is 0 or 1; m is 0 or 1; k is 0 or 1; Z1, Z2, and Z3 are each independently a single bond, —C═C—, —OCO—, —COO—, —CF2O—, or a C1 to C5 alkylene group; X1, X2, X3, and X4 are each independently hydrogen or halogen; Y is hydrogen, an alkylene group, an alkoxy group, a hydroxyl group, —NHCOCH3, or ═O; and A and B are cyclic compounds.

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.
