Claim:
1. A manufacture method of a color filter, comprising: sequentially deposing a metal layer and a black matrix layer on a substrate, and the substrate comprises a color filter area, a black matrix area and a through hole area; implementing a patterning process to the black matrix layer with a half tone mask to entirely remove the black matrix layer in the color filter area, to partially remove the black matrix layer in the through hole area, and to entirely reserve the black matrix layer in the black matrix area; removing the metal layer in the color filter area and the black matrix layer in the through hole area to form a black matrix and a through hole; coating a RGB color filter layer in the color filter area to form an array of RGB color filters; wherein the black matrix area includes an array of through holes, each is provided in between two adjacent RGB color filters; and deposing a transparent metal layer on the substrate to form a transparent electrode; wherein the black matrix of the black matrix area encircles the through hole area, and through the hole area of the structure is positioned in the black matrix area.
