Production of liquid crystal color display element

Abstract

Abstract PURPOSE:To obtain a liquid crystal color display element with which flattening of a substrate surface in the stage of forming color filter parts by printing can be executed and which can prevent color deviation by forming a resin layer on the color filter parts and flattening the rugged surfaces. CONSTITUTION:Red, green and blue inks are printed on one substrate 2 made of glass constituting a liquid crystal cell to form the color filter parts (1R, 1G, 1B) of the respective colors as shown in the figure A. A polyester film 12 on which an epoxy resin to be formed as a resin layer 11 is coated by screen printing is press-stuck onto the color filter parts 1 of the substrate 2 by a roller 14 while said film is heated by a heating means 13. The viscosity is decreased by the heating and the epoxy resin of the resin layer 11 is filled closely between the film 12 and the substrate 2 by pressing. A glass plate is imposed on the film 12 in succession thereto and the epoxy resin is cured under the uniform pressure exerted thereto. The film 12 is thereafter stripped and the substrate 2 formed with the resin layer 11 shown in the figure C is obtd. The resin surface 15 formed in such a manner is smooth and has ruggedness of several mum or below.
