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.

Abstract: A touch sensor may include a base substrate, a sensing unit including a first electrode and a second electrode provided on a same layer of the base substrate and not overlapping with each other, wherein a capacitance of the sensing unit is changed by a user's touch, and a cushion layer disposed on at least one surface of the sensing unit and configured to have a permittivity change in response to a pressure of the user's touch, wherein the cushion layer may include an insulator and conductive particles and the insulator may include an elastic material elastically deformed by the pressure of the user's touch.
