1. A transparent colored layer provided in a pattern on a pixel portion on a transparent substrate for coloring transmitted light of the pixel portion for each color, and a gap portion (inter-pixel portion) between each pixel on the transparent substrate. In a method for manufacturing a color filter substrate for a liquid crystal display device, which is provided with a pattern and which shields light transmission from this portion, after forming the light shielding portion and the transparent colored layer on the transparent substrate in sequence. An overcoat layer is provided on the entire surface including the light-shielding portion and the transparent coloring layer, a transparent electrode layer is further provided on the entire surface, and then a positive photosensitive resin paint is printed or applied on the transparent electrode layer. After that, the liquid crystal display is characterized in that a gap regulating layer is formed on the transparent electrode layer by exposing and developing the same from the transparent substrate side to remove the photosensitive resin on the pixel portion. For equipment Color filter substrate manufacturing method.
