Patent ID: 8025939

Claim:
A liquid crystal display comprising: a pair of substrates, at least one of said substrates being transparent; a liquid crystal layer disposed between said pair of substrates; a group of electrodes formed on one of said pair of substrates for applying an electric field having a component substantially in parallel with a surface of said substrate to said liquid crystal layer; an alignment control film disposed between said liquid crystal layer and at least one of said pair of substrates; and optical means formed on at least one of said pair of substrates, for changing an optical property of said liquid crystal layer in accordance with an alignment state of molecules of said liquid crystal layer, wherein at least one of said alignment control films is an alignment control film consisting of photoreactive polyimide and/or polyamic acid provided with an alignment control ability by irradiation of substantially linearly polarized light, and wherein an anchoring energy in the azimuth direction at an interface of the alignment control film and the liquid crystal layer is 2.3×10 −4 N/m or more.
