摘要:
Disclosed herein are an organic electroluminescent (EL) device comprising a hole transport layer (HTL) and a method for fabricating the same. The organic electroluminescent (EL) device comprises a stack in which a light-emitting layer and a hole transport layer are interposed between an anode and a cathode, wherein the hole transport layer is made of a mixture of at least two materials, and wherein the mixture is selected from a mixture of an organic compound and one or more other organic compounds, a mixture of a metal or inorganic compound and one or more other metal or inorganic compounds, and a mixture of one or more organic compounds and one or more metal or inorganic compounds.
