Abstract:
The present application discloses a method of fabricating a color filter substrate, including forming a black matrix layer including forming a plurality of black matrices on a base substrate thereby defining a plurality of subpixel areas, the plurality of black matrices being formed to have a plurality of pores; dispensing a first color filter material in a plurality of first subpixel areas of the plurality of subpixel areas thereby forming a first color filter material layer, the first color filter material permeating into pores of black matrices adjacent to the plurality of first subpixel areas; and forming a first color filter layer. Subsequent to forming the first color filter layer, the first color filter material remains in at least a first portion of the black matrices adjacent to the plurality of first subpixel areas.
