PURPOSE:To prevent a light shield film pattern from being broken owing to charged-up static electricity by constituting a conductive film area surrounding a light shield film area as one continuous area. CONSTITUTION:A chromium film 2 on a glass substrate 1 forms the continuous conductive area surrounding the light shield area so that eight corner areas among P11-P57 have corners cut. Thus, the large conductive area is formed to evade discharge even in the case of a charge-up state, so the pattern is not broken. When the chromium film is left in the continuous state, the chromium film 2 is formed on the transparent glass substrate 1 and a positive resist film 3 is formed thereupon; and the periphery is coated with a protective film 4 formed by blackening a polyvinyl-alcohol solution with dye and then exposed, so that the resist below the protective film 4 is not exposed and left as a mask. Consequently, the chromium film at the periphery can be left. |
