Abstract

The present invention provides a color filer substrate in which color pixels of a plurality of colors are formed in the predetermined regions delimited by a bank-like delimiting member on the surface of a base member, and protective layer is formed on the color pixels, the surface of the protective layer is modified so as to have excellent flatness. The color filter substrate can include a bank-like delimiting member having a predetermined height formed on a base member so as to delimit color-pixel-forming regions on a surface of the base member, color pixels formed in the color-pixel-forming regions by arranging liquid color pixel materials, and a protective layer formed on the surfaces of the color pixels by arranging a liquid protective layer material. The delimiting member can be composed of a resin having repellency to the color pixel material and the protective layer material. The surface of the delimiting member can be subjected to surface treatment to decrease the repellency to the liquid material constituting the protective layer.
