According to one embodiment, a display device includes a display area, a plurality of sensor electrodes and a shield electrode. The display panel includes a first substrate, a second substrate opposed to the first substrate, a liquid crystal layer sealed between the first substrate and the second substrate, a pixel electrode, and a counter-electrode. The plurality of sensor electrodes are arranged to surround the display area. The shield electrode is arranged between the plurality of sensor electrodes and the pixel electrode or the counter-electrode located closest to a boundary between the display area and a non-display area surrounding the display area, in planar view. A predetermined reference voltage is applied to the shield electrode.
