Abstract: A display device according to an embodiment includes a pixel and a bank. The pixel includes sub-pixels and an emission area including sub-emission areas corresponding to the sub-pixels. The bank surrounds the emission area. The pixel includes electrodes disposed in each of the sub-emission areas, at least one light emitting element disposed in each of the sub-emission areas, and bank patterns disposed under the electrodes, the bank patterns overlapping a portion of the electrodes. The bank patterns include a first bank pattern including a first valley, the first bank pattern being disposed in a first edge area of the emission area in a first direction. The bank patterns include a second bank pattern including a second valley, the second bank pattern being disposed in a second edge area of the emission area in the first direction.

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.
