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.
