Abstract
A display device includes a base layer, a circuit element layer, a display element layer, a thin film encapsulation layer, and a touch sensing layer. The base layer includes a display area and a non-display area bordering the display area. The circuit element layer includes first driving circuits and second driving circuits disposed in the non-display area of the base layer, and a pixel driving circuit disposed in the display area of the base layer. The display element layer in the display area of the base layer includes display elements provided on the circuit element layer. The touch sensing layer includes a plurality of touch electrodes that receive a touch sensing signal from the second driving circuit to eliminate being routed to a pad area to supply touch sensing signals to the touch electrodes.
