Organic electroluminescence device with mixed hole transporting materials

摘要

An organic electroluminescent device (10) is disclosed which has a cathode (16), an electron transporting zone (15), an emitting zone (14), an hole transporting zone (13) and an anode (12) that are laminated in sequence. The hole transporting zone (13) includes at least one hole transporting layer fabricated with two or more homogeneously mixed hole transporting materials each having a glass transition temperature above 75 DEG C and which are structurally compatible.
