More Information
Summary:An organic electroluminescence device including a lower electrode disposed on a substrate, an organic layer having at least a light emission layer and disposed above the lower electrode, and upper electrode having a transparent conductive film and disposed above the organic layer, in which the device has an electron injecting layer between the organic layer and the upper electrode. The electron injecting layer has a buffer layer comprising an insulative material and a mixed layer comprising an organic material that has an electron transporting property and a metal material that has an electron injecting property.
