Abstract

A display device includes: a display layer; plural first electrodes formed to be arranged above the display layer; a shield electrode formed apart from the plural first electrodes so as to surround the whole plural first electrodes along an arrangement surface; an insulating layer; and a semiconductive layer formed opposite to the first electrodes and the shield electrode so as to sandwich the insulating layer, wherein the difference between an average potential of the first electrodes and an average potential of the shield electrode is equal to or less than 0.5V.

Claims (15)

1. A touch detection device comprising:

a transparent substrate;

plural touch detection electrodes arranged on the transparent substrate;

a shield electrode arranged on the transparent substrate, the shield electrode being apart from the plural touch detection electrodes;

an insulating layer arranged on the plural touch detection electrodes and the shield electrode; and

a semiconductive layer arranged on the insulating layer,

wherein the insulating layer is arranged between the semiconductive layer and a layer including the plural touch detection electrodes and the shield electrode, and

the difference between an average potential of the touch detection electrodes and an average potential of the shield electrode is equal to or less than 0.5V.

2. The touch detection device according to claim 1 ,

wherein the average potential of the shield electrode is equal to or higher than the average potential of the touch detection electrodes.

3. The touch detection device according to claim 1 ,

wherein gaps between the shield electrode and the touch detection electrodes are approximately the same as or larger than a gap of two touch detection electrodes adjacent to each other.

4. The touch detection device according to claim 1 ,

wherein the shield electrode is made of the same material as the touch detection electrodes, and

the shield electrode and the touch detection electrodes have transparency.
