Abstract
A liquid crystal display device of the present invention includes a thin-film transistor substrate, a counter substrate facing the thin-film transistor substrate, a liquid crystal layer provided between the thin-film transistor substrate and the counter substrate, an alignment film provided on the thin-film transistor substrate; a sealing material which bonds together the thin-film transistor substrate and the counter substrate at the periphery of the liquid crystal layer, and a polymerized layer provided on the liquid crystal layer-side surface of the alignment film. The alignment film contains a first polymer and a second polymer of a different type from that of the first polymer and is chemically bonded to the sealing material, the first polymer and the second polymer contained in the alignment film are mixed in a surface layer in contact with the liquid crystal layer, and the first polymer and the second polymer have different photo-functional groups.
