    摘要: A light emitting diode device, an array substrate and a display device. The light emitting diode device includes a substrate, a first sub-light emitting unit disposed on the substrate, and a second sub-light emitting unit disposed on a side of the first sub-light emitting unit away from the substrate. The first sub-light emitting unit includes a first semiconductor layer of a first conductivity type, a first light emitting layer, and a second semiconductor layer of a second conductivity type which are each disposed successively in a direction away from the substrate. The second sub-light emitting unit includes the second semiconductor layer, a second light emitting layer, and a third semiconductor layer of the first conductivity type. Each layer is disposed successively in the direction away from the substrate. The first conductivity type is different from the second conductivity type.
