Organic Light Emitting Diode and Method of Fabricating the Same

摘要

An organic light emitting diode includes a first electrode on a substrate; a hole transporting layer on the first electrode; a light emitting material layer on the hole transporting layer; an electron transporting layer on the light emitting material layer and doped with a metal; a second electrode on the electron transporting layer; and a buffer layer between the electron transporting layer and the second electrode and using an organic material of a triphenylene skeleton including substituted or nonsubstituted heteroatom, or a substituted or nonsubstituted Pyrazino quinoxaline derivative compound.
