Abstract: The present disclosure provides a display device that includes an insulating layer disposed on a substrate. The display device further includes a plurality of first electrodes and contact electrodes disposed on the insulating layer. The display device further includes a plurality of light-emitting elements disposed on the plurality of first electrodes. The display device further includes a second electrode disposed on the plurality of light-emitting elements. The display device further includes a passivation layer covering the first electrode. The display device further includes a first opening hole at the passivation layer. The first opening hole extends through the passivation layer. The passivation layer has a first opening hole exposing a portion of an upper surface of the first electrode.
