Abstract
A display device having an electrostatic capacity touch panel includes: X electrodes XP and Y electrodes YP which intersect each other via a first insulating layer; and a plurality of Z electrodes disposed in a floating state via a second insulating layer. For the second insulating layer, a material such as an elastic insulating material which changes in thickness by pressing of touch is used. The Z electrode is disposed so as to overlap both one of the X electrodes and one of the Y electrodes. A pad part of the X electrode has a largest area in the vicinity of a thin line part of the X electrode, and a smallest area in the vicinity of the thin line part of the adjacent X electrode. An area of the pad part is reduced as the pad part departs from the thin line part of the X electrode.
