Production of liquid crystal color display element

Abstract

Abstract PURPOSE:To prevent the color deviation of a liquid crystal color display element and to reduce the cost of production by printing and forming opaque parts at prescribed intervals on the inside surface of one substrate, printing and forming color filter parts between the opaque parts and flattening these parts. CONSTITUTION:An opaque material of black color, etc. is printed at prescribed intervals on the inside surface of one substrate, i.e., the substrate 2 consisting of transparent glass to form the opaque parts 4. Inks 5 for red, green and blue (5R, 5G, 5B) to be made into the color filter parts 1 are printed onto the substrate 2 between the opaque parts 4 and are fixed. The surfaces of the inks 5R, 5G, 5B are polished by using a lapping film consisting of alumina and silicon carbide until the average ink thickness attains 5mu. An insulation coating material of epoxy is coated thereon by a doctor knife method to form a coating layer 6. A transparent electrode layer 7 consisting of, for example, ITO and further an oriented layer 8a are formed on the layer 6.
