Abstract: Among data voltages applied to a plurality of pixels on a display panel, a first data voltage is shifted from a first original data voltage by a first value, a second data voltage is shifted from a second original data voltage by a second value, and a third data voltage is shifted from a third original data voltage by a third value to compensate for AC and DC afterimages. A common voltage generator provides an optimal common voltage for the third data voltage when the temperature of the liquid crystal panel assembly is lower than a reference temperature and provides an optimal common voltage for the first data voltage or the second data voltage when the temperature of the liquid crystal panel assembly is higher than or equal to the reference temperature. The first, second, and third values correspond to respective kickback voltages of the respective gray level data voltages.

Abstract: A liquid crystal photo-alignment agent includes a polyimide copolymer including a first structure unit represented by the described Chemical Formula 1 and a second structure unit represented by the described Chemical Formula 2, and, based on a 100 mole % sum total of the first structure unit and the second structure unit, the first structure unit is included in an amount of 70 to 95 mole % and the second structure unit is included in an amount of 5 to 30 mole %. A liquid crystal photo-alignment film may be manufactured using the same, and a liquid crystal display may include the liquid crystal photo-alignment film.

Abstract: A photoalignment agent includes a polyimide and a capping terminal connected to a main chain end terminal of the polyimide. The capping terminal includes an alkylene group (—CmH2m—, m is a natural number) and a core stereo unit in a dendrimer format. A liquid crystal display includes a first substrate, a thin film transistor disposed on the first substrate, a first electrode connected to the thin film transistor, and a first alignment layer disposed on the first electrode. The first alignment layer includes a polyimide and a capping terminal connected to a main chain end terminal of the polyimide. The capping terminal includes an alkylene group (—CmH2m-, m is a natural number) and a core stereo unit in a dendrimer format.
