发明名称 COLOR FILTER AND ITS PRODUCTION
摘要 PROBLEM TO BE SOLVED: To prevent faulty display such as an afterimage, etc., from occurring by setting the tilt angle of the surface of a color filter on the pattern edge part of a black matrix to be smaller than a specified value. SOLUTION: This color filter is provided with the black matrix 24 and a coloring layer 26 formed on the aperture part of the black matrix 24 and a part of the black matrix 24 on a transparent base plate 22. The layer 26 is flat in the vicinity of the center of the aperture part of the black matrix 24 but swells on the pattern edge part of the black matrix 24 because of the black matrix 24. It is conceivable to form a transparent protective film 28 and a transference electrode 30 on the layer 26 as necessary but the swell on the black matrix 24 is not eliminated. By grinding the surface of the layer 26, the tilt angle &theta; of the layer 26 on the pattern edge part of the black matrix 24 is set to <=25 deg.. It is desirable to set the thickness of the layer 26 to >=1.6 &mu;m.
