Abstract:
A liquid crystal display including 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, wherein the first alignment layer includes polyimide and a capping group connected to a main chain end of the polyimide, and the capping group contains at least one of a first compound represented by the following Chemical Formula 1, and a second compound represented by the following Chemical Formula 2: A1 and A2 are, independently of each other, an aromatic compound having 4 to 20 carbon atoms or an aliphatic cyclic compound having 4 to 20 carbon atoms; and B1 and B2 are, independently of each other, a crosslinking reaction group containing an alkylene group (—CnH2n—, n is a natural number).
