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 a RGB color filter;
- and
- deposing a transparent metal layer on the substrate to form a transparent electrode.
A color filter, comprising:
- a substrate, comprising a color filter area, a black matrix area and a through hole area;
- a RGB color filter, positioned in the color filter area;
- a metal layer, positioned in the black matrix area and the through hole area of the substrate;
- a black matrix, positioned on the metal layer in the black matrix area;
- and
- a transparent electrode, positioned on the RGB color filter, the metal layer in the through hole area and the black matrix.
A liquid crystal display panel, comprising an array substrate, a color filter and a liquid crystal layer positioned between the array substrate and the color filter;
- wherein the color filter comprises:
- a substrate, comprising a color filter area, a black matrix area and a through hole area;
- a RGB color filter, positioned in the color filter area;
- a metal layer, positioned in the black matrix area and the through hole area of the substrate;
- a black matrix, positioned on the metal layer in the black matrix area;
- and
- a transparent electrode, positioned on the RGB color filter, the metal layer in the through hole area and the black matrix.
