Abstract: PURPOSE:To uniformize a cell gap by using a material prepd. by preliminarily dispersing gap materials uniformly into a color filter material. CONSTITUTION:The gap materials 9 to be used to maintain the cell gap of a liquid crystal element are dispersed into a resin for constituting picture elements of a color filter and after the resin is coated on a substrate 1, a colored layer 11 having a pattern shape provided with the gap materials 9 by a photolithographic stage is formed on the substrate 1. More specifically, the gap materials 9 are preliminarily dispersed into the resin having the photosensitivity to constitute the picture element material of the color filter. A coloring material is thereafter patterned by UV rays via a pattern mask and the color filter layer contg. the gap materials 9 is formed by the photolithographic method. The gap materials 9 are otherwise dispersed into a non-photosensitive resin and after the picture element pattern is formed by using such resin, the color filter layer contg. the gap materials 9 is formed by a dyeing stage.
