A touch panel includes first touch electrodes, second touch electrodes, and third touch electrodes. The first touch electrodes include sub electrodes spaced apart from one another in a first direction. The second touch electrodes extend in a second direction crossing the first direction. The second touch electrodes are spaced apart from one another in the first direction. The third touch electrodes extend in the second direction and are spaced apart from one another in the first direction. The third touch electrodes are shaped differently than the second touch electrodes.
