    Abstract: A touch electrode line is divided in the active area in a structure in which touch routing lines are coupled to both sides of the touch electrode line, so that resistance and parasitic capacitance may be reduced due to the touch electrode line and the touch routing line. In addition, a dummy pattern is disposed between the divided touch electrode lines, so that it is possible to easily implement an arrangement structure of the touch electrode line with improved touch sensing performance by preventing a short circuit defect between the divided touch electrode lines due to static electricity.
