Abstract: A display device includes: a bank on a base layer, the bank forming an opening; an alignment electrode layer on the base layer, the alignment electrode layer including a first alignment electrode and a second alignment electrode spaced from each other in a first direction; and a light emitting element between the first alignment electrode and the second alignment electrode. The opening includes a first area and a second area. The first area and the second area are arranged along a second direction different from the first direction. The first area has a first width along the first direction. The second area has a second width along the first direction. The first width is greater than the second width.

Abstract: A display device includes a substrate and a pixel on the substrate. The pixel has an alignment area, and the alignment area has a first alignment area, a second alignment area spaced apart from the first alignment area in a first direction, and a non-alignment area extending around a periphery of the alignment area. The pixel includes: a first electrode and a second electrode extending in the first direction across the alignment area and being spaced apart from each other; a first bank in the non-alignment area and extending along a boundary of the pixel; an alignment control layer including a first alignment control pattern, the first alignment control pattern being spaced apart from the first bank in the non-alignment area between the first alignment area and the second alignment area; and a first light emitting element between the first electrode and the second electrode in the first alignment area.
