Abstract:
A method of forming a color filter on a substrate having pixel driving elements, comprising the steps of:providing a substrate having a plurality of light-transmitting areas and active areas; forming a pixel driving element on the substrate in each active area, wherein an insulation layer is formed between each pixel driving element and on the substrate in the light-transmitting areas; forming a planarization layer on the pixel driving elements and the insulation layer; wherein planarization layer consists of organic high polymer removing part of the planarization layer to form a plurality of contact holes and openings, wherein the contact holes expose part of the surface of the pixel driving elements, and the openings expose the surface of the insulation layer in the light-transmitting areas; filling at least one color pigment into the openings to form a color filter on the substrate having the pixel driving elements; and forming transparent pixel electrodes in the contact holes to electrically connect the pixel driving elements, wherein the transparent electrodes extend onto part of the color filter.
