Patent ID: 8487901

Claim:
A display device having a capacitance touch panel, characterized in that said 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, a third insulating layer is formed over the Z electrodes, and a 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.
