Organic electroluminescent element and the manufacturing method

摘要

One embodiment of an organic electroluminescent element of present invention includes a substrate, a first electrode on the substrate, an organic luminescent medium layer including an organic luminescent layer on the first electrode, a second electrode on the organic luminescent medium layer and barrier film formed on the second electrode. The organic luminescent medium layer is sandwiched between the first electrode and the second electrode. Film density of the barrier film changes in thickness direction.
