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<EnL−EF1≰4 eV (1) EpH−EnL≰1 eV (2) where EF1 is a Fermi energy level of the conductive layer of the first electrode, EnL is an LUMO energy level of the n-type organic compound layer of the first electrode, and EpH 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.
