Organic electroluminescent element, method of manufacturing organic electroluminescent element, lighting device, and display device

摘要

An objective in the present invention is to provide an organic EL element exhibiting high emission efficiency and long lifetime, together with a lighting device and a display device thereof. In the present invention, disclosed is an organic electroluminescent element comprising a support substrate provided thereon an anode and a cathode, the organic electroluminescent element comprising an organic layer containing a reactive organic compound between the anode and the cathode, wherein the reactive organic compound contained in the organic layer has nonuniform concentration at any point in time between termination of a process of preparing the organic electroluminescent element and a start of electricity application to the organic electroluminescent element.
