| 摘要 |
A white organic light emitting diode device (10), comprising first (100) and second (380) electrodes facing each other above a substrate (50), first (160) and second (250) charge generation layers formed between the first electrode and the second electrode, a first stack (ST1) disposed between the first electrode and the first charge generation layer and including a first light emitting layer (140), a second stack (ST2) disposed between the first charge generation layer and the second charge generation layer and including a second light emitting layer (230), and a third stack (ST3) disposed between the second charge generation layer and the second electrode and including a third light emitting layer (330), wherein two of the first to third light emitting layers emit a blue light and the rest light emitting layer emits a yellow-green light. |
