Abstract: A display device includes a display panel including pixels and a scan driver for driving the pixels. The pixels are in a display area and the scan driver is in a non-display area. A touch sensing unit is disposed on the display panel and includes touch electrodes disposed in a sensing area and touch sensing lines connected to the touch electrodes. The non-display area includes at least one multiplexer, the touch sensing lines are electrically connected to input terminals of the at least one multiplexer through touch contact holes formed on the display panel. Sensing channels electrically connected to output terminals of the multiplexer are parallel to the scan driver. The at least one multiplexer is disposed between the sensing channels and the scan driver.

Abstract: A display device includes a substrate including a display area and a non-display area outside the display area, a plurality of pixels located in the display area, a driving circuit driving the pixels, and a pad portion located in the non-display area and electrically connected to the driving circuit through a plurality of outer wirings. The pad portion includes a plurality of pad wirings each electrically connected to corresponding ones of the outer wirings. The pad wirings includes a first pad wiring and a second pad wiring separated from each other. The first pad wiring includes a first electrode layer, an insulating layer on the first electrode, and a second electrode layer on the insulating layer in a stacking direction, the second electrode layer being connected to the first electrode layer. The second pad wiring includes the first electrode layer but not the second electrode layer.
