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 translation: 用于触摸面板的第一电极30形成在对置基板200的外侧上，并且保护膜210形成在第一电极30上以覆盖它。 保护膜210中的缺陷211通过喷墨涂布与另一保护膜210填充。 保护膜210的表面被摩擦到粗糙的表面光洁度。 偏光板220通过粘合剂材料221附着在保护膜210的粗糙表面上。由于通过形成保护膜210来修复缺陷区域，因第一电极（布线）30的存在而导致的腐蚀 可以防止粘合材料221，并且由于第二保护膜210的表面变得粗糙，所以粘附表面积的增加增加了用于附着偏光板220的粘附。
