Abstract: A display device includes sub-alignment areas including a pathway area defined by a first adjacent electrode and a second adjacent electrode spaced apart from each other in a first direction. A pathway area includes a first pathway area and a second pathway area spaced apart from each other along a second direction different from the first direction. The first adjacent electrode of the first pathway area and the first adjacent electrode of the second pathway area are spaced apart from each other with an open area therebetween. The second adjacent electrode of the first pathway area and the second adjacent electrode of the second pathway area are spaced apart from each other with the open area therebetween.

Abstract: A display device includes: a first light emitting element located between the first and second patterns; a first alignment electrode located on the first pattern, the first alignment electrode having a first inclined surface opposing the first light emitting element; a first connection electrode at a same layer as the first alignment electrode; and first and second electrodes electrically connected to respective end portions of the first light emitting element. Each of the first alignment electrode and the first connection electrode includes first and second electrode layers that are sequentially stacked. A contact hole exposing the first electrode layer of the first connection electrode is formed in the second electrode layer of the first connection electrode. The first electrode is in contact with the first electrode layer of the first connection electrode and a side surface of the second electrode layer of the first connection electrode through the contact hole.
