Abstract
To provide: a color filter substrate with high display quality in which defective portions of a bank member (black matrix), such as a pin hole, a portion having an insufficient film thickness, a portion having an insufficient width, and a disconnection portion, or color mixing defects of a colored layer are corrected by the simple and inexpensive method; a liquid crystal display device including such a color filter; and production methods thereof. The color filter substrate of the present invention is a color filter substrate comprising a bank member and a colored layer on a substrate, wherein the color filter substrate has a structure in which a color mixing member formed of colored layer materials of two or more colors is formed in a defective portion of the bank member or along the bank member.
