Patent ID: 8537125

Claim:
A display device having an electrostatic capacity touch panel that detects touch position coordinates in a display region by an electrostatic capacity coupling method, wherein the electrostatic capacity touch panel comprises: a plurality of X electrodes; a plurality of Y electrodes; a plurality of Z electrodes; each of the plurality of X electrodes and each of the plurality of Y electrodes intersect each other via a first insulating layer, and are formed so as to alternately array pad parts and thin line parts in extending directions of each of the plurality of X electrodes and each of the plurality of Y electrodes, and the pad part of each of the plurality of X electrodes and the pad part of each of the plurality of Y electrodes are disposed so as not to overlap each other in plan view; each of the plurality of Z electrodes is formed via a second insulating layer so as to overlap both of one of the plurality of X electrodes and one of the plurality of Y electrodes which are adjacent to each other in plan view, and the plurality of Z electrodes are disposed in an electrically floating state; in plan view, a width of the pad part of each of the plurality of Y electrodes in the extending direction of each of the plurality of X electrodes is constant with respect to the extending direction of each of the plurality of Y electrodes; in plan view, the pad part of each of the plurality of X electrodes and the pad part of each of the plurality of Y electrodes are alternately disposed in the extending direction of each of the plurality of X electrodes; each of the plurality of Z electrodes is divided by a plurality of slits in the extending direction of each of the plurality of Y electrodes; and the plurality of slits dividing the plurality of Z electrodes are arranged above at least one of a center of the pad parts of the plurality of X electrodes and a center of the pad parts of the plurality of Y electrodes.
