Abstract: A touch sensor includes a base layer and a plurality of first touch electrodes disposed on the base layer. The plurality of first touch electrodes are arranged in a first direction. The plurality of first touch electrodes include openings, and are electrically connected to one another. A plurality of second touch electrodes are disposed on the base layer. The plurality of second touch electrodes are arranged in a second direction. The plurality of second touch electrodes are electrically connected to one another. First pressure sensing electrodes and second pressure sensing electrodes are separated from each other and are disposed in the openings. The pressure sensing electrodes and second pressure sensing electrodes are spaced apart from the first touch electrodes. The first pressure sensing electrodes, the second pressure sensing electrodes, the first touch electrodes, and the second touch electrodes are all disposed in a first layer.
