Claim:
1. A display device, comprising: a first substrate having a display area in which pixels each having a thin-film transistor are arranged in a matrix on an insulating surface; a second substrate that is arranged opposite to the first substrate; an organic EL element layer that is arranged above the first substrate and between the first substrate and the second substrate, and emits light under control by a circuit including the thin film transistor; a first sealing film which is arranged above the organic EL element layer, covers the organic EL element layer, and includes at least a first inorganic layer made of inorganic material; a plurality of first detection electrodes that extend in one direction, and are arranged in parallel above the first sealing film; a second sealing film that is arranged above the first detection electrodes and the first sealing film, configured to planarize an uneven surface of the first sealing film and the plurality of first detection electrodes, and includes at least a second inorganic layer made of an inorganic material; a plurality of second detection electrodes that extend in another direction different from the one direction, and are arranged in parallel above the second sealing film; and a touch sensor control unit that controls a potential of any one of the first detection electrodes and the second detection electrodes, and detects an electric change generated in the other detection electrodes to detect a touch with a display surface.
