ABSTRACT:
There is provided a plastic liquid crystal display device in which an aligning film processing can be carried out at 150 to 180.degree. C. and which can have optical characteristics comparable to those of the conventional glass substrate liquid crystal display device. The plastic liquid crystal device comprises a pair of plastic substrates, transparent electrodes, insulating films for protecting the electrodes, aligning films and a liquid crystal, wherein the aligning film is an aligning film which is formed by dissolving a high-temperature sintering organic polymer aligning film made of polyimide or a polyimide-like substance in a solvent, printing a resulting solution thereof on a substrate, removing only the solvent by heating and/or heating under reduced pressure, and sintering the substrate at 200.degree. C. or less.
