Estimating the term…
A liquid crystal display cell, wherein orientation films are made of an organic polymer such as polyimide, polyamide, liquid crystal polymer having one or more mesogen groups in a main chain or side chain and produced by spreading an organic polymer solution on a water surface, is excellent in memory properties and contrast and generates no static electricity, no short circuit between electrodes and no breaking of electrodes.
A liquid crystal display cell comprising two spaced substrates having transparent electrodes arranged thereon in desired display patterns, a liquid crystal composition being sealed between the inner surfaces of said two substrates by a sealant, and two orientation films being arranged on individual transparent electrodes, at least one of said orientation films having an infrared dichroic ratio of 1.05 or more and a single layer film thickness of 0.003 .mu.m or more and being obtained by spreading a solution of an organic polymer on a water surface and picking up a produced film.
