Document Type and Number:
Japanese Patent JP5491020
Kind Code:
B2
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.
