Display panel, display device, and tiled display device

A tiled display device comprising a first display panel and a second display panel, wherein

• the first display panel includes:
• a first substrate unit including a first base substrate, a first gate line disposed on the first base substrate, and a first data line disposed on the first base substrate;
• and
• a second substrate unit including a second base substrate, disposed on the first substrate unit and shifted in a predetermined direction with respect to the first substrate unit in a plan view, thereby being divided into a first region overlapping the first substrate unit and a second region non-overlapping the first substrate unit, and
• the second display panel includes:
• a third substrate unit including a third base substrate, a second gate line disposed on the third base substrate, and a second data line disposed on the second base substrate;
• and
• a fourth substrate unit including a fourth base substrate, disposed on the third substrate unit and shifted in a predetermined direction with respect to the third substrate unit in the plan view, thereby partially overlapping the third substrate unit, wherein the third base substrate is divided into a third region overlapping the fourth substrate unit and a fourth region non-overlapping the fourth substrate unit in the plan view, and the second region partially overlaps the fourth region in the plan view, and
• further comprising a conductive tape disposed in an overlap region,
• wherein the conductive tape is adhered to the first substrate unit and the third substrate unit, and
• wherein the overlap region, in which the second region and the fourth region overlap each other, is defined between the first region and the third region in the plan view.
