Abstract: A touch panel includes a first touch electrode disposed on a base substrate and a second touch electrode disposed on an insulating layer, which is disposed over the first touch electrode. The first touch electrode includes a first linear pattern disposed along a first direction and a first protrusion pattern extending from the first linear pattern. The second touch electrode includes a second linear pattern disposed along a second direction crossing the first direction and a second protrusion pattern extending from the second linear pattern. Wires connect the first touch electrode and the second touch electrode to a driving circuit. The second protrusion pattern partially overlaps the first protrusion pattern.
