Abstract: A display device includes a substrate. A first electrode, a second electrode, and a third electrode are on the substrate, and are sequentially arranged along a first direction. A first light emitting element is located between the first electrode and the second electrode. A second light emitting element is located between the second electrode and the third electrode. A first contact electrode overlaps the first electrode and one end of the first light emitting element, and is in contact with the first electrode and the one end of the first light emitting element. A second contact electrode overlaps and is in contact with the other end of the first light emitting element. A third contact electrode overlaps and is in contact with the second electrode and the other end of the second light emitting element. The second contact electrode extends while detouring the third contact electrode.
