DISPLAY DEVICE
First Claim
1. A display device having a capacitance touch panel, characterized in thatsaid capacitance touch panel comprises a number of X electrodes, a number of Y electrodes, and a number of Z electrodes,said X electrodes and said Y electrodes cross with a first insulating layer in between and are formed so that respective pad portions and fine wire portions are aligned alternately in the direction in which the electrodes extend, and thus, the pad portions of said X electrodes and the pad portions of said Y electrodes are aligned without overlapping as viewed in a plane,said Z electrodes are formed with a second insulating layer in between so that each Z electrode overlaps both an adjacent X electrode and Y electrode as viewed in a plane,said number of Z electrodes are electrically floating from each other, anda pulse signal is sequentially applied to one set of said X electrodes or Y electrodes and a change in the signal is detected from the other set of electrodes.

Abstract
The display device is provided with X electrodes XP and Y electrodes YP which cross with a first insulating layer in between and a number of Z electrodes which are electrically floating from each other with a second insulating layer in between. The Z electrodes are arranged so that each Z electrode overlaps both an adjacent X electrode and Y electrode. The pad portion of a first X electrode has such a form that the area is maximum in the vicinity of the fine wire portion of the first X electrode and the area is minimum in the vicinity of the fine wire portion of an adjacent second X electrode, and the area of the pad portion is smaller towards the direction in which the distance increases away from the vicinity of the fine wire portion of the first X electrode. A pulse signal is sequentially applied to one set of X electrodes or Y electrodes.
