Abstract
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.

A display device comprising:
- a display area comprising 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;
- a seal configured to seal the liquid crystal layer between the first substrate and the second substrate;
- a plurality of sensor electrodes arranged to surround the display area;
- and
- a shield electrode which 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, and to which a predetermined reference voltage is applied, in planar view, wherein
- the shield electrode is arranged to surround the display area,
- the plurality of sensor electrodes are arranged to surround the shield electrode, and
- at least one of the shield electrode, the detection electrode, or a drive electrode overlaps with the seal.
