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.
