Abstract
According to one embodiment, a display device includes a base, a display unit containing pixels, a power supply circuit, a touch controller and a switching circuit disposed between the display unit, the power supply circuit and the touch controller. The pixels each includes a pixel circuit and a display element including a lower electrode connected to the pixel circuit, an upper electrode disposed to oppose the lower electrode and an organic layer including a light-emitting layer disposed between the lower electrode and the upper electrode. The upper electrode is connected to the switching circuit, and the switching circuit selectively switches between connecting the upper electrode to the power supply circuit and connecting the upper electrode to the touch controller.
