Abstract: A display device includes a display panel, a plurality of first sensing electrodes disposed on the display panel, and a plurality of second sensing electrodes disposed on the first sensing electrodes and isolated from the first sensing electrodes. A wire width of each first sensing electrode of a second group is smaller than a wire width of each first sensing electrode of a first group, and a wire width of each second sensing electrode of a fourth group is smaller than a wire width of each second sensing electrode of a third group.
