COA SUBSTRATE, DISPLAY APPARATUS, AND METHOD FOR MANUFACTURING COA SUBSTRATE

摘要

A color filter on array (COA) substrate, a display apparatus, and a method for manufacturing the COA substrate. The COA substrate comprises: a base substrate (200); a thin film transistor array (210) disposed on the base substrate (200); a protective layer (220) covering the thin film transistor array (210); and a color filter comprising color pixels (230)and white pixels (240). The white pixels (240) are made of a photoresist material. The color pixel region and the white pixel region of the COA substrate have a small segment difference, and a white resin material is not needed to perform development, thereby saving the cost.
