Abstract: PROBLEM TO BE SOLVED: To provide heat resistant color filters which have excellent flatness used for color sepn., reflection prevention and display contrast improvement used for a display having a high-temp. process in production process and have an improved substrate adhesion property and reflectivity decrease. SOLUTION: This heat resistant color filters are constituted by forming black matrices 10, colored patterns 11 and an over-coating layer 12 covering these matrices and patterns and having light transparency on a transparent substrate 1. The surface of the transparent substrate of the portions formed with the black matrices of the heat resistant color filters is roughened. Since the surface of the transparent substrate of the portions formed with the black matrices is roughened, the reflection on the surface in these portions is scattered and the components returning by direct reflection are relatively decreased and, therefore, the drastic decrease of the surface reflectivity is made possible.
