摘要:
The present disclosure relates to an organic electroluminescent device comprising a first electrode, a second electrode facing the first electrode, a light-emitting layer between the first electrode and the second electrode, and an electron transport layer and an electron buffer layer between the light-emitting layer and the second electrode. An organic electroluminescent device having low driving voltage, high luminous efficiency and/or long lifespan can be provided by comprising the compound of the present disclosure in an electron buffer layer and an electron transport layer.
