A method of manufacturing a black matrix of a color filter includes forming a light-shielding layer of a hydrophobic organic material on a surface of a transparent substrate, forming a blocking layer of a fluorinated resin on a top surface of the light-shielding layer, patterning the light-shielding layer and the blocking layer to form the black matrix, the black matrix having a top surface formed with the blocking layer, and heating the black matrix formed with the blocking layer and irradiating UV light towards an upper portion of the black matrix.
