Abstract:
A display device includes: a display panel including a plurality of pixels; a plurality of driving electrodes disposed on the display panel and extending in a first direction; a plurality of sensing electrodes disposed on the driving electrodes and extending in a second direction; a plurality of first sensing wires connected to one end of each of the driving electrodes; a plurality of second sensing wires connected to each of the sensing electrodes; a plurality of third sensing wires connected to the other end of each of the driving electrodes that are disposed in a partial region; and a touch controller configured to apply a touch detection signal to the driving electrodes through the first sensing wires and the third sensing wires, and to receive a sensing signal representing a change in capacitance of the sensing electrodes through the second sensing wires, so as to detect a touch position.
