    Abstract: A display device includes a first electrode, a second electrode disposed spaced apart from the first electrode in a first direction, and an element part disposed between the first electrode and the second electrode. The element part includes light-emitting elements that have a shape extending in one direction and are arranged spaced apart from each other in a second direction perpendicular to the first direction; and a binder surrounding each of the light-emitting elements and fixing the light-emitting elements. The one direction in which the light-emitting elements extend is parallel to the first direction.

    Abstract: A display device includes a light emitting element disposed on a substrate and including a first end portion and a second end portion. The first electrode is electrically connected to the first end portion of the light emitting element. The second electrode is electrically connected to the second end portion of the light emitting element. A first semiconductor layer, a light emitting layer, a second semiconductor layer, and an electrode layer of the light emitting element are sequentially disposed along a longitudinal direction from the second end portion to the first end portion. An insulating film of the light emitting element covers side surfaces of the first semiconductor layer, the light emitting layer, the second semiconductor layer, and the electrode layer, and extends in parallel to the longitudinal direction. A shielding layer is disposed inside the insulating film.
