A display device includes two or more pixels disposed in a pixel area in which two or more data lines intersect two or more gate lines; a common electrode commonly disposed on the pixels; a first gate high voltage supplied through a first gate voltage line, a portion of the first gate high voltage overlapping the common electrode; a second gate high voltage supplied through a second gate voltage line, a portion of the second gate high voltage overlapping the common electrode; a connecting line structure in contact with the common electrode, and extending from the common electrode in a direction toward a position in which the common electrode does not overlap the first gate voltage line.
