Abstract

PURPOSE:To obtain a high-density display pattern by oxidation-processing the whole surface of a metal mesh into an insulator, coating a conducting thin film on the whole surface except the boundary sections of grids, end forming multiple grids electrically separated by insulating boundary sections. CONSTITUTION:The whole surface or a metal grid mesh 11 is oxidation- processed, and an oxide film 12 is formed on the whole surface to insulate electrically. Al, for example, is stuck on the oxide film 12 by the sputtering method to form a conducting metal thin film 13, and multiple grid meshes 15a, 15b are dividedly formed by a grid mesh division section 14. Individual grid meshes 15a, 15b are connected to lead-out terminals 17 formed on a glass substrate 1 with communicating wires 16. The grids 15a, 15b adjacent to each other are thereby located nearby, and a high-density display pattern can be obtained.
