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.

Abstract: The present invention provides a substrate for display device, in which display quality can be improved by suppressing generation of a region not filled with liquid material for functional film (ink) in formation of a functional film, such as a colored layer in a color filter substrate of a liquid crystal display device and an organic layers such as a luminous layer and a positive hole transporting layer in an organic electroluminescent display device, by an application method such as an ink jet method, and a liquid crystal display panel, a liquid crystal display device and an organic electroluminescent device each comprising the substrate for display device. The substrate for display device according to the present invention comprises a bank on the substrate, the bank having a structure with a chamfered corner.
