摘要：
The present invention relates to an organic electroluminescent device, particularly to an organic light emitting diode (OLED) including an ETL stack of at least two electron transport layers, wherein the first electron transport layer comprises a first electron transport matrix compound and the second electron transport layer comprises second electron transport matrix compound and a redox n-dopant, and a device comprising the OLED.
