Abstract: A touch sensing unit includes first touch electrodes, a first touch signal line, and a second touch signal line. The first touch electrodes are disposed in a touch sensor area. The first touch signal line is electrically connected to some of the first touch electrodes arranged in a first column. The second touch signal line is electrically connected to some of the first touch electrodes arranged in a second column different from the first column. The second touch signal line includes a first bent portion bent at least once in an intersection region of the first touch signal line and the second touch signal line.

Abstract: A touch unit is provided including a touch electrode disposed in a sensor region. A touch driving wire is connected to the touch electrode. The touch driving wire includes a first routing line connected to a first side of the touch electrode and a second routing line branched from the first routing line and connected to a second side of the touch electrode. A pad electrode line is spaced apart from the touch driving wire. The pad electrode line is connected to a pad. A pad connection line is connected to the touch driving wire and the pad electrode line. The pad connection line is disposed in a different layer from the touch driving wire. An area in which the pad connection line is in contact with the first routing line is greater than an area in which the pad connection line is in contact with the pad electrode line.
