摘要： A display device includes a bank layer disposed on a substrate and defining an emission area, a first to sixth alignment electrodes, each disposed on the substrate extending across the emission area, spaced apart from each other, and sequentially arranged in a direction, a first light emitting element disposed between the first alignment electrode and the second alignment electrode in the emission area and emitting first light, a second light emitting element disposed between the third alignment electrode and the fourth alignment electrode in the emission area and emitting second light, and a third light emitting element disposed between the fifth alignment electrode and the sixth alignment electrode in the emission area and emitting third light. Wavelengths of the first light, the second light, and the third light are different from each other.

摘要： A display device includes an electrode layer including a first electrode and a second electrode that are spaced apart from each other and disposed on a substrate, a light emitting element between the first electrode and the second electrode, and a capping layer disposed on the light emitting element and including at least one low refractive layer and at least one high refractive layer that are alternately disposed. The capping layer includes a first low refractive layer on the electrode layer and the light emitting element, a first high refractive layer on the first low refractive layer, and a second low refractive layer on the first high refractive layer. A thickness of the first low refractive layer is greater than a thickness of the second low refractive layer.

摘要： A display device includes a substrate; a first electrode and a second electrode disposed in an emission area and a sub-region and spaced apart from each other in a first direction; a first insulating layer disposed on the first electrode and the second electrode; light emitting elements disposed on the first insulating layer in the emission area, and including ends disposed on the first and second electrodes, respectively; and a second insulating layer disposed on the first insulating layer. The second insulating layer includes a fixing pattern; a support pattern portion; and a connection portion electrically connecting the fixing pattern and the support pattern portion, and the fixing pattern includes a first region that contacts an outer surface of the light emitting elements and a second region that does not contact the outer surface of the light emitting elements.
