An organic electroluminescent (EL) element and a method of manufacturing the same are provided. The EL element comprises an organic light emitting layer, an electron transport layer, an electron injection layer, an electrode formed on an upper side of a substrate, and a buffer layer. The buffer layer is formed between the electron transport layer and the electron injection layer, or between the electron injection layer and the electrode by an atomic layer deposition process. Thus, interfacial properties of the electron injection layer and the electrode are improved. Accordingly, leakage current at a threshold voltage or less of the EL element is prevented, and an electric property of the EL element is improved.
