Abstract: A display panel includes a substrate, a light-emitting structure layer, a specular reflection layer and an interference adjustment layer. The light-emitting structure layer is located on a side of the substrate. The light-emitting structure layer has a plurality of light-emitting regions and a non-light-emitting region for spacing the plurality of light-emitting regions apart from each other. The specular reflection layer is located on a side of the light-emitting structure layer away from the substrate. The specular reflection layer covers at least the non-light-emitting region. The interference adjustment layer is located on a side of the specular reflection layer away from the light-emitting structure layer. The interference adjustment layer is configured such that lights of some colors interfere destructively to form a mirror display of a set color.
