1. A touch panel comprising:
first touch electrodes comprising sub electrodes spaced apart from one another in a first direction;
second touch electrodes extending in a second direction crossing the first direction, the second touch electrodes being spaced apart from one another in the first direction; and
third touch electrodes extending in the second direction and spaced apart from one another in the first direction, the third touch electrodes being shaped differently than the second touch electrodes,
wherein:
the first touch electrodes and the second touch electrodes are configured to detect, independent of the third touch electrodes, a first touch of a first touch input member;
the third touch electrodes are configured to detect a second touch of a second touch input member different from the first touch input member,
the first touch electrodes and the second touch electrodes are configured to output, in a first touch mode, signals to detect coordinates of the first touch; and
the second touch electrodes and the third touch electrodes are configured to output, in a second touch mode different from the first touch mode, signals to detect coordinates of the second touch.
