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: According to one embodiment, a sensor-equipped display device includes a display panel, first driver, and second driver. The display panel includes a common electrode, a pixel electrode, a detection electrode, a connection line and lead line. The first driver supplies a common driving signal to the common electrode during a display drive time and supplies a sensor driving signal to the common electrode during a sensing drive time. The second driver detects a sensor output value during the sensing drive time. The lead line and the common electrode are apart from each other with a certain gap at least during the sensing drive time.
