Abstract:
A touch panel having high durability is provided. Either one or both of a display device and a flexible panel have island-shaped protective bodies formed on surfaces of electrode layers (upper electrode layer, lower electrode layer), and a transparent conductive film is exposed between the protective bodies. Since the protective bodies protrude highly from the surface of the transparent conductive film, when the flexible panel is pressed and the upper electrode and the lower electrode layer are brought into contact, a load to be applied to the transparent conductive film is reduced by the protective bodies, so that the transparent conductive film is not broken.
