Abstract: A touch sensing unit includes a first touch electrode disposed in a touch sensor area. A second touch electrode is disposed in the touch sensor area. A first touch line is disposed in a touch peripheral area. The first touch line is electrically connected to the first touch electrode. The touch peripheral area is disposed on a periphery of the touch sensor area. A second touch line is disposed in the touch peripheral area. The second touch line is electrically connected to the second touch electrode. The touch peripheral area includes first and second regions. In the first region, a width of the first touch line is smaller than a width of the second touch line. In the second region, the width of the first touch line is equal to the width of the second touch line.
