Display device

A display device includes: a display panel having a display area and a non-display area at least partially disposed around the display area; and a touch sensor disposed on the display panel and including a touch sensor area in the display area and a touch peripheral area in the non-display area adjacent to the touch sensor area, wherein the touch sensor includes: a first touch electrode and a second touch electrode; a first touch pad and a second touch pad being adjacent to each other in a first direction; a second touch pad disposed in a touch pad area of the touch peripheral area; a first touch signal line electrically connecting the first touch electrode with the first touch pad, the first touch signal line including a first line portion extended in the first direction and a second line portion extended in a second direction; a second touch signal line electrically connecting the second touch electrode with the second touch pad; a first dummy line extended in the first direction and spaced apart from the first and second touch signal lines; and a second dummy line extended in the first direction and spaced apart from the first and second touch signal lines.

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.
