A display device includes alignment electrodes spaced apart from each other, first and second light emitting elements between the alignment electrodes, a first pixel electrode electrically connected to first end portions of the first light emitting elements, a second pixel electrode electrically connected to second end portions of the first light emitting elements, a third pixel electrode electrically connected to the second pixel electrode and to first end portions of the second light emitting elements, a fourth pixel electrode electrically connected to second end portions of the second light emitting elements, and an insulating layer between the first pixel electrode and the second pixel electrode, wherein the insulating layer includes at least one opening exposing the second end portions of the first and second light emitting elements.

Display device with improved light emission efficiency

A display device includes a first electrode and a second electrode disposed on a substrate, the first and second electrodes extending in a first direction in parallel to each other, a first insulating layer disposed on the first and second electrodes, light-emitting elements disposed on the first insulating layer, the light-emitting elements including first end portions disposed on the first electrode and second end portions disposed on the second electrode, an oxide semiconductor layer disposed on the first insulating layer and the light-emitting elements, the oxide semiconductor layer including a first conductive portion electrically contacting the first end portions of the light-emitting elements, a second conductive portion electrically contacting the second end portions of the light-emitting elements, and a semiconductive portions disposed between the first and second conductive portions, and a second insulating layer disposed on the oxide semiconductor layer.

Display device

A display device includes an emission area and a sub-region spaced apart from the emission area in a first direction, electrodes extending in the first direction, disposed across the emission area and the sub-region, and spaced apart from each other in a second direction, a first bank surrounding the emission area and the sub-region, and light emitting elements disposed on the electrodes spaced apart in the second direction in the emission area. The first bank includes trench portions in which a top surface of the first bank is partially depressed. The trench portions are disposed between the emission area and the sub-region.
