Abstract: A display panel includes a driving back plate, a first insulating layer, and a light-emitting device layer sequentially stacked. The driving back plate includes a first reflecting electrode layer. The first reflecting electrode layer includes first primary reflecting electrodes in a display area and first auxiliary reflecting electrodes in a peripheral area. The light-emitting device layer includes a second reflecting electrode layer including second primary reflecting electrodes in the display area and second auxiliary reflecting electrodes in the peripheral area. The second primary reflecting electrodes are in one-to-one correspondence and electrically connected with the first primary reflecting electrodes. The orthographic projection of the second primary reflecting electrode on the first reflecting electrode layer are located within the first primary reflecting electrode.
