Abstract
According to an aspect, a display device with a touch sensor has a display function and a touch sensor function. The display device includes: a panel unit that comprises a first substrate, a second substrate, and a display function layer between the first substrate and the second substrate; a first electrode on the first substrate; a second electrode on the second substrate; a third electrode on the second substrate; and a capacitor for the touch sensor function. The capacitor is formed between either of the first electrode and the second electrode and the third electrode, or between both the first electrode and the second electrode and the third electrode. The frame portion outside the display area comprises, on the first substrate side thereof, a peripheral circuit, and the second electrode is provided in a position more distant upward from the peripheral circuit than the first electrode.
