    Abstract: A liquid crystal display device includes a first substrate, a first alignment film disposed on the first substrate, a second substrate, and a liquid crystal layer disposed between the first alignment film and the second substrate. The first substrate has a surface curved in a first direction and the second substrate has a surface curved in the first direction. The first alignment film includes a polymerization initiator and a polymer chain that is a copolymer of a dianhydride-based compound and a diamine-based compound. The polymer chain includes a main chain including a repeating unit including an imide group, a first side chain, including a vertical align group, bonded to the main chain, and a second side chain bonded to the main chain. The functional group includes a biphenyl group or a terphenyl group.
