Patent ID: 8597861

Claim:
A method for producing a color filter, comprising: (a) forming a black matrix pattern having a surface tension of 26 to 45 mN/m on a substrate; (b) performing a plasma treatment of the substrate on which the black matrix pattern is formed; and (c) filling a pixel unit defined by the black matrix pattern by using an ink, wherein the plasma treatment is performed by using CF 4 gas, wherein the forming of the black matrix pattern comprises: (a1) applying a photosensitive resin composition on the substrate; (a2) prebaking the photosensitive resin composition to form a black matrix film; and (a3) selectively exposing and developing the formed black matrix film and then performing postbaking, wherein the ink has a surface tension of 20 to 30 mN/m, and wherein the surface tension of the formed black matrix pattern is higher than the surface tension of the ink.
