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 (—CH—, 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.
