Claim:
1. A method of manufacturing a color filter, comprising: step 1, at least forming black matrix electrodes, first electrodes, second electrodes and third electrodes insulated from each other on a base substrate; and step 2, at least forming a black matrix layer, a first color filter pattern, a second color filter pattern and a third color filter pattern on the base substrate using an electrophoretic deposition process respectively by the black matrix electrodes, the first electrodes, the second electrodes and the third electrodes; wherein the step 1 comprises: forming the black matrix electrodes with a plurality of opening areas on the base substrate, the plurality of opening areas of the black matrix electrodes defining at least a first sub-pixel area, a second sub-pixel area and a third sub-pixel area; forming an insulating layer on a side of the black matrix electrode facing away from the base substrate; and forming the first electrodes, the second electrodes and the third electrodes on a side of the insulating layer facing away from the black matrix electrodes, wherein the first electrodes are formed in portions of the side corresponding to the first sub-pixel areas, the second electrodes are formed in portions corresponding to the second sub-pixel areas and the third electrodes are formed in portions corresponding to the third sub-pixel areas.
