First Claim
1. A display device comprising:
- a capacitive touch panel,the capacitive touch panel including a plurality of X-electrodes, a plurality of Y-electrodes, and a Z-electrode,the X-electrode and the Y-electrode intersecting with each other via a first insulating layer at an intersecting portion, each of the X-electrode and the Y-electrode being formed such that pad portions and fine line portions are alternately arranged in its extending direction, the pad portion of the X-electrode and the pad portion of the Y-electrode being arranged so as not to overlap each other as viewed in plan,the Z-electrode being formed so as to overlap, via a second insulating layer, both the X-electrode and the Y-electrode neighboring to each other as viewed in plan,the Z-electrode being electrically floating,one of the X-electrode and the Y-electrode being sequentially applied with a pulse signal, and a change in the signal being detected from the other electrode, whereinthe Z-electrode is formed of an elastic conductive material, andthe intersecting portion is formed in a different layer from the X-electrode or the Y-electrode.

Abstract
In a display device including a capacitive coupling touch panel, reaction to touch with nonconductive input means is achieved, and highly accurate position detection is realized with a small number of electrodes even with a small touch area. X-electrodes and Y-electrodes which intersect with each other via a first insulating layer and a Z-electrode which is in a floating state via a second insulating layer are disposed. For the Z-electrode, a material whose thickness changes by pressing due to touch, such as an elastic conductive material, is used. The Z-electrode is arranged so as to overlap both the X-electrode and the Y-electrode neighboring to each other. A pad portion of the X-electrode has a shape such that an area is maximized in the vicinity of a fine line portion of the relevant X-electrode.
