Abstract
According to one embodiment, a display device includes a first substrate, a second substrate opposing the first substrate, a liquid crystal layer, at least one first detection electrode disposed in a display area and a plurality of second detection electrodes disposed in a peripheral area. In a display period in which images are displayed on the display area, a predetermined voltage is applied to the first detection electrode to drive the liquid crystal layer, and in a period in which the liquid crystal layer is not driven, the first detection electrode is set to a state of being not electrically connected to anywhere or being connected to a predetermined potential with an impedance of 50 kΩ or higher.
