Abstract
A display device includes a display panel configured to display an image, and a sensor provided on at least one surface of the display panel and configured to sense a touch location and a touch pressure. The sensor includes a sensing unit having sensing electrodes formed on a same layer, and of which a capacitance changes according to a touch, and a resistance element disposed on the sensing unit, and of which a resistance changes according to a pressure of the touch. Accordingly, touch and touch intensity can both be sensed.
