Color filter substrate, liquid crystal display device, production method of color filter substrate, production method of liquid crystal display device

A production method of a color filter substrate comprising a bank member and a colored layer having at least two light-transmissive regions separated by the bank member on a substrate, wherein the bank member is corrected by forming a color mixing member formed of two or more intermixed colored layer materials each of a single color in a defective portion of the bank member or along the bank member, and

• forming the different single-color light-transmissive regions of the colored layer respectively using each of the colored layer materials.

A production method of a color filter substrate comprising a bank member, at least part of the bank member being constituted by a black matrix, and a colored layer having pixel regions separated by the bank member on a substrate, wherein the production method of the color filter substrate comprises:

• detecting a defective portion of the bank member, adding a colored layer material-containing droplet of a respective single color in each pixel region adjacent to the defective portion of the bank member such that the droplets mix at the defective portion, wherein the droplets that mix at the defective portion are two or more of colored layer materials each of a single different color, and different single-color light-transmissive regions of the colored layer corresponding to each pixel region, are respectively formed from each of the different colored layer materials;
• and
• removing a colored layer in one of the pixel regions adjacent to the defective portion of the bank member while not removing a portion formed in the other of the both adjacent pixel regions and a portion alternatively used as the bank member.
