Abstract: A display device includes light-emitting elements disposed on an array substrate. The array substrate includes a substrate, switch elements disposed on the substrate, an insulating layer, a connecting layer, a conductive layer and a spacer layer. The insulating layer is disposed on the switching elements and has through holes. The connecting layer is disposed on the insulating layer and is electrically connected to the switching elements through the through holes. The conductive layer is disposed on the connecting layer and includes pads electrically connected to the connecting layer. The spacer layer disposed between the connecting layer and the conductive layer. The conductive layer extends on the spacer layer and is orthographically projected on the substrate to form a first orthographic projection area, where the through holes are located in the first orthographic projection.
