1. A display electrode, comprising:
a reflective layer; and
two double-layer adjusting units stacked on the reflective layer, each double-layer adjusting unit comprising an insulating layer and a conductive layer sequentially arranged and directly contacted in a direction away from the reflective layer,
wherein for at least one of the two double-layer adjusting units, a via hole is provided in the insulating layer, an electrode lead formed integrally with the conductive layer is provided in the via hole, and the conductive layer is electrically connected to the reflective layer through the electrode lead,
wherein in each double-layer adjusting unit, a difference between a thickness of the conductive layer and a thickness of the insulating layer does not exceed a set threshold, and the set threshold is configured to control the thickness of the insulating layer,
wherein the conductive layer farthest from the reflective layer locates on different levels in light-emitting regions of different types of light-emitting devices.
