Abstract

A method of manufacturing a color filter is provided. The method includes: forming at least black matrix electrodes, first electrodes, second electrodes and third electrodes insulated from each other on a base substrate; and depositing at least a black matrix layer, a first color filter pattern, a second color filter pattern and a third color filter patter on the base substrate using an electrophoretic deposition process respectively by means of the black matrix electrodes, the first electrodes, the second electrodes and the third electrodes. A color filter and a display device are also provided. The described solution provides a process which is simple, convenient to operate, ease of control, and allows fast film formation.
