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.
