Abstract: A first electrode 30 for the touch panel is formed on an outer side of a counter substrate 200, and the protection film 210 is formed over the first electrode 30 to cover it. A defect 211 in the protection film 210 is filled in with another protection film 210 by inkjet coating. The surface of the protection film 210 is rubbed to a rough surface finish. The polarization plate 220 is attached to the rough surface of the protection film 210 via an adhesive material 221. Since the defective region is repaired by the formation of the protection film 210, corrosion of the first electrode (wiring) 30 due to the presence of the adhesive material 221 can be prevented, and since the surface of the second protection film 210 is made rough, a resulting increase in adhering surface area enhances the adhesion for attaching the polarization plate 220.

Abstract: A manufacturing process of an electrode substrate includes a step of forming a protective layer so as to cover a conductor pattern by applying raw material liquid discharged as droplets to an upper surface of a substrate in a first region and a second region of the upper surface of the substrate. At this time, an application amount of the raw material liquid per unit area in the second region is made smaller than an application amount of the raw material liquid per unit area in the first region, so that an average film thickness of the protective layer of a portion formed in the second region is made smaller than an average film thickness of the protective layer of a portion formed in the first region.
