Top-emission type organic electroluminescent element and top-emission type organic electroluminescent device

A top-emission type organic electroluminescent element, comprising:

• a first electrode;
• an organic functional layer, disposed on the first electrode;
• and
• a second electrode, disposed on a side of the organic functional layer facing away from the first electrode;
• wherein the second electrode comprises a work-function adjustment layer and a transparent metal oxide layer, the work-function adjustment layer is disposed on the side of the organic functional layer facing away from the first electrode, and the transparent metal oxide layer is disposed on a side of the work-function adjustment layer facing away from the organic functional layer;
• wherein the second electrode further comprises:
• a charge generation layer, disposed between the work-function adjustment layer and the transparent metal oxide layer;
• and
• wherein the charge generation layer comprises a first-type charge generation layer and a second-type charge generation layer, the first-type charge generation layer is disposed on the side of the work-function adjustment layer facing away from the organic functional layer, and the second-type charge generation layer is disposed between the first-type charge generation layer and the transparent metal oxide layer.
