Abstract: A display device may include: a substrate including a display area and a non-display area; and pixels in the display area, and each including sub-pixels. Each sub-pixel may include a pixel circuit layer, and a display element layer including at least one light emitting element. The display element layer may include: a first electrode on the pixel circuit layer; a second electrode on the first electrode and electrically insulated from the first electrode; the light emitting element including a first end portion coupled to the first electrode and a second end portion coupled to the second electrode, and between the first electrode and the second electrode; an intermediate layer enclosing at least one area of the light emitting element, and on the first electrode; a connection line electrically connected to the second electrode. The second electrode may be on the intermediate layer.

Abstract: A method of aligning light emitting elements includes applying a ground voltage to a first electrode and applying a first AC voltage to a second electrode spaced apart from the first electrode; and applying a ground voltage to the first electrode and applying a second AC voltage to the second electrode, wherein the first AC voltage has an asymmetric waveform.
