| Zusammenfassung: | An organic luminescence display device having an emission layer between a first electrode and a second electrode is disclosed. One embodiment of the device includes: a first hole injection layer and a second hole injection layer between the first electrode and the emission layer; and a charge generation layer doped with a p-type dopant between the first hole injection layer and the second hole injection layer. The device has a reduced driving voltage and an enhanced efficiency and lifetime. |
