Abstract: A display device includes: a substrate; a first bank including a first sub-bank and a second sub-bank spaced apart from each other on the substrate; a first electrode on the first sub-bank; a second electrode on the second sub-bank and spaced apart from the first electrode; and a light-emitting element between the first sub-bank and the second sub-bank. Each of the first and second sub-banks has a first area having a concave curved shape in a cross section and being adjacent to the light-emitting element. The first electrode has a first section extending beyond the first sub-bank toward the light-emitting element, the second electrode has a first section extending beyond the second sub-bank toward the light-emitting element, and a width of the first section of the first electrode is different from a width of the first section of the second electrode.

Abstract: A display device may include a first electrode and a second electrode spaced from each other on a substrate. A light emitting element may be on the first electrode and the second electrode. A first insulating pattern may be on the light emitting element. A first contact electrode may be on a first side of the first insulating pattern and contacting a first end of the light emitting element. A second insulating pattern may be on the first insulating pattern and partially covering the first contact electrode. A third insulating layer may be on the second insulating pattern. A second contact electrode may be on a second side of the first insulating pattern, and contact a second end of the light emitting element that is exposed from the first insulating pattern, the second insulating pattern, and the third insulating layer.

Abstract: A display device includes electrodes spaced apart from each other, light emitting elements disposed between the electrodes, and connection electrodes electrically connected to the light emitting elements. The connection electrodes include first areas in electrical contact with the light emitting elements and second areas extending upwardly from the light emitting elements. A space is formed between the light emitting elements and the second areas of the connection electrodes.
