Abstract: A display back panel may include a substrate, an insulating layer disposed on one side of the substrate and including a plurality of recesses, the plurality of recesses including a bottom surface, a first electrode disposed on a surface of the insulating layer away from the substrate, a pixel defining layer disposed on a surface of the first electrode away from the substrate and including a plurality of openings, a light-emitting layer disposed in the plurality of openings and covering the first electrode, and a second electrode disposed on a surface of the light-emitting layer away from the substrate. Therein, the first electrode may reflect waveguide light laterally propagated by the light-emitting layer, thereby improving a light-emitting efficiency of the light-emitting layer. Further, the reflected waveguide light may not be absorbed by the second electrode, thereby enhancing an external quantum effect of the light-emitting layer.
