1. A display device comprising:
a display panel comprising a display area defined by a first direction and a second direction crossing the first direction;
a first circuit board apart from the display panel in the second direction;
a second circuit board apart from the display panel in the second direction and apart from the first circuit board in the first direction; and
a coupling film coupled to the display panel, and electrically connecting the first circuit board and the second circuit board,
wherein the coupling film comprises:
a first coupling part extending along the second direction and coupled to the display panel and the first circuit board;
a second coupling part apart from the first coupling part in the first direction, and the second coupling part coupled to the display panel and the second circuit board; and
a third coupling part extending along the first direction and electrically connecting the first coupling part and the second coupling part, and
wherein a first end portion of the third coupling part at least partially overlaps the display panel and the first coupling part in a top plan view, and a second end portion of the third coupling part at least partially overlaps the display panel and the second coupling part in the top plan view.
