Abstract

A display panel comprises includes: a base substrate; a first electrode layer and a second electrode layer on a side of the base substrate; a light-emitting layer between the first electrode layer and the second electrode layer; and a carrier functional layer located at least one of between the first electrode layer and the light-emitting layer, and between the second electrode layer and the light-emitting layer. The light-emitting layer has a plurality of light-emitting portions with different emergent light wavebands; and the carrier functional layer has a plurality of carrier functional portions corresponding to the plurality of light-emitting portions, the plurality of carrier functional portions having molecular chains, which is formed by cross-linking of monomers containing functional groups under light irradiation.
