Abstract: A display device includes a first substrate, a second substrate, a display functional layer, first electrodes, pixel electrodes, second electrodes, a drive circuit, and a conductive body. The second substrate faces the first substrate. The display functional layer is provided between the first substrate and the second substrate. The first electrodes are provided between the first substrate and the second substrate. The pixel electrodes face the first electrodes between the first substrate and the second substrate. The second electrodes overlap the first electrodes through the display functional layer. The drive circuit supplies drive signals to a pair of the first electrode, wherein the drive circuit supplies a first electric potential to one of the pair of first electrodes and supplies a drive signal having a second electric potential different from the first electric potential to the other of the pair of first electrodes simultaneously.

Abstract: According to one embodiment, a sensor-equipped display device includes first electrodes and a detection electrode. The first electrodes constitute sensor drive electrodes by being supplied with sensor drive signals separately and sequentially or sensor drive electrodes by simultaneously supplying the sensor drive signals to the first electrodes adjacent to each other. A width of the sensor drive electrode including the first electrode on the edge is smaller than a width of the other sensor drive electrode not including the first electrode on the edge.
