ORGANIC ELECTRONIC DEVICE

摘要

Disclosed is an electronic device including an n-type organic compound layer as a portion of an electrode for hole injection or hole extraction. The electronic device includes a first electrode including a conductive layer and an n-type organic compound layer disposed on the conductive layer; a second electrode; and a p-type organic compound layer that is interposed between the n-type organic compound layer of the first electrode and the second electrode and forms an NP junction together with the n-type organic compound layer of the first electrode and energy levels of the layers satisfy the following Expressions (1) and (2): 2 eV < E_nL - E _Fl = 4 eV (l) E _pH - E _nL =1 eV (2) where E _Fl is a Fermi energy level of the conductive layer of the first electrode, E _nL is an LUMO energy level of the n-type organic compound layer of the first electrode, and E_pH is an HOMO energy level of the p-type organic compound layer forming the NP junction together with the n-type organic compound layer of the first electrode.
