    Abstract: A display device includes a substrate, first electrodes, pixel electrodes, a display functional layer, common electrodes, second electrodes stacked in this order. The display device further includes lines that are provided between the substrate and the display functional layer and intersect with the first electrodes in the plan view. In response to a control signal from a controller, the pixel electrodes are supplied with a pixel signal through the lines, and the common electrodes are supplied with a common signal in the display periods; either of the lines and the first electrodes are supplied with a first drive signal to generate a magnetic field, and the other thereof generate an electromotive force caused by the magnetic field in the first sensing period; the common electrodes are supplied with a second drive signal to generate electrostatic capacitance between the common electrodes and the second electrodes in the second sensing period.
