Organic light emitting device and method for manufacturing the same
Disclosed is an organic light emitting device and a method for manufacturing the same. The organic light emitting device includes a first electrode, one or more organic compound layers, and a second electrode. The first electrode includes a conductive layer and an n-type organic compound layer disposed on the conductive layer. A difference in energy between an LUMO energy level of the n-type organic compound layer of the first electrode and a Fermi energy level of the conductive layer of the first electrode is 4 eV or less. One of the organic compound layers interposed between the n-type organic compound layer of the first electrode and the second electrode is a p-type organic compound layer forming an NP junction along with the n-type organic compound layer of the first electrode. A difference in energy between the LUMO energy level of the n-type organic compound layer of the first electrode and an HOMO energy level of the p-type organic compound layer is 1 eV or less. One or more layers interposed between the conductive layer of the first electrode and the second electrode is n-doped or p-doped with an organic material or an inorganic material.
