Title: Method of manufacturing a liquid crystal device with plane alignment

Abstract: A method of manufacturing devices in which a liquid crystal has molecules orientated in accordance with directions belonging to one and the same plane, is provided. To this end, an organic polymer deposit is formed upon the internal faces of two electrode-carrying plates, by directing on to them at a very low angle of incidence, a monomer vapor flow, for example a monomer such as vinyl-trichlorosilane. The long-chain molecules of the in situ formed polymer, are disposed parallel to the direction of the vapor flow. They orientate, by their influence, the molecules of the liquid crystal.
