Abstract: Disclosed is a display device including an input sensor. The input sensor includes a first group electrode and a second group electrode that overlap a sensing region. The first group line is connected to the first group line, and overlaps the sensing region. The first group line is substantially uniformly located in a first region of the sensing region, and is located more densely in a second region of the sensing region than in the first region. A length of the first group line located in the second region is less than that of the first group line located in the first region.
