TRANSMISSIVE SUBSTRATE WITH LIGHT SHIELDING FILM FOR COLOR LIQUID CRYSTAL DISPLAY DEVICE AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To provide a light shielding film which has practically a sufficient high light shielding ratio for and a low back surface reflection and has a good etched profile. SOLUTION: The light shielding film 2 of the transmissive substrate 3 with the light shielding film for a color liquid crystal display device which has the transmissive substrate 1 and the light shielding film 2 selectively formed on the surface of the substrate 1 and is used to improve the contrast of the image of the color liquid crystal display device is formed of a layer contg. a chromium oxide. The oxidation degree of the chromium oxide at the end face of the light shielding film 2 on the substrate 1 side is made larger than the oxidation degree of the chromium oxide at the other end face facing the end face described above and the oxidation degree of the chromium oxide incorporated into the light shielding film 2 is continuously changed from the end face on the substrate 1 side toward the other end face.
