  • Publication number: 20240413128
    Abstract: A display device includes a first electrode and a second electrode which are spaced apart from each other on a substrate. A light emitting element is disposed between the first electrode and the second electrode. A light emitting element core of the light emitting element includes a first semiconductor layer, a second semiconductor layer spaced apart from the first semiconductor layer, and a light emitting layer disposed between the first semiconductor layer and the second semiconductor layer. A first element insulating layer surrounds a side surface of the light emitting element core. The first element insulating layer is an oxide insulating layer having a single crystalline structure.

  • Publication number: 20240304760
    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.
