Abstract: A display device includes a pixel disposed in a display area. The pixel includes a first electrode and a second electrode spaced apart from each other; a light emitting element disposed between the first electrode and the second electrode and including a first end portion and a second end portion; a third electrode disposed on the first end portion of the light emitting element and electrically connecting the first end portion to the first electrode; and a fourth electrode disposed on the second end portion of the light emitting element and electrically connecting the second end portion to the second electrode. An opening is formed in at least one of the first to fourth electrodes and disposed in a first area and a second area that are adjacent to the first end portion and the second end portion of the light emitting element.
