A compound light-emitting layer and a manufacturing method therefor, and a white-light organic electroluminescent device. The compound light-emitting layer comprises a first light-emitting layer (141) and a second light-emitting layer (142), wherein the first light-emitting layer (141) comprises polyfluorene or a polyfluorene derivative, and the second light-emitting layer (142) comprises quantum dots. The compound light-emitting layer can reach various colour gamuts, and can increase the brightness of a device at the same time. |
