PURPOSE:To prevent the generation of an irregular pattern, and to improve the hue and color tint with uniform lightness over the whole surface, by immersing a plate which has formed an oriented film on an insulating substrate, into a warm bath. CONSTITUTION:A plate which has formed an ITO layer 2 and an oriented film 6 in a parallel line shape on a glass substrate 1 is immersed in a warm bath 3 of about 90 deg.C for 30 minutes, and the surface layer of the film 6 is softened. Subsequently, many thin grooves are formed in the same direction on the surface layer of the oriented film 6 by rubbing. Two pieces of substrates 1 re opposed and stuck through a spacer 4 in the direction where the ITO electrodes 2 of a parallel line shape are orthogonal to each other, and its gap is sealed with a liquid crystal 5. Accordingly, the generation of an irregular pattern is decreased remarkably, the lightness becomes uniform on the whole surface, and excellent hue and color taste can be obtained.
