Abstract: A scan driver for display device includes: a plurality of stage groups each including a first stage and a second stage spaced apart from the first stage in a first direction; and a first power line extending in the first direction, the first power line being commonly electrically connected to the plurality of stage groups. The first power line includes a first branch line extending in a second direction crossing the first direction between the first stage and the second stage, and the first branch line is electrically connected to the first stage and the second stage. The first stage includes a first transistor including a first electrode connected to a first scan line and a second transistor including a first electrode connected to a first sensing line, and the second stage includes a third transistor including a first electrode connected to a second scan line and a fourth transistor including a first electrode connected to a second sensing line. The first transistor, the second transistor, the third transistor, and the fourth transistor disposed one after the other in the first direction.
