Abstract: A display device includes first touch electrodes, first routing lines, second routing lines, and a first guard line. The first touch electrodes are arranged in a touch sensing area. The first routing lines are connected to one side of the first touch electrodes. The second routing lines are connected to another side of the first touch electrodes. The first guard line is between the first routing lines and the second routing lines, and includes a first region extending in a first direction, and a second region extending from one end of the first region in a second direction crossing the first direction. The first region includes a first touch conductive layer, and a second touch conductive layer on the first touch conductive layer. The second region of the first guard line includes the second touch conductive layer and does not overlap the first touch conductive layer.
