摘要:
Disclosed is a self light-emitting element including a first electrode, a light-emitting layer disposed above the first electrode, a function layer disposed above the light-emitting layer, and doped with a metal, and a second electrode disposed above the function layer, in which the function layer has a multilayer structure of at least three layers including an uppermost layer, a lowermost layer, and an intermediate layer between the uppermost layer and the lowermost layer, and the intermediate layer is doped with the metal at a lower concentration than the uppermost layer and the lowermost layer.
