Abstract
Abstract A plastic liquid crystal display device having top coats (insulating films) which can be set at 200° C. or less without resort to ultraviolet light and have appreciable flexibility. The plastic liquid crystal display device comprises a pair of plastic substrates, transparent electrodes, insulating films for protecting the transparent electrodes, aligning films and a liquid crystal, wherein the insulating film (top coat) is formed by dispersing any one of acryl-silanic resin, epoxy-silanic resin and silanic resin in a solvent to provide a solution, coating the solution on the transparent electrode and sintering a resulting coating at 200° C. or less.
