ABSTRACT:
To provide an organic EL device and a method of manufacturing the same, having light-emitting characteristics enhanced by capturing selectively mobile metal ions, the organic EL device includes between a first electrode and a second electrode, a functional layer having at least a light-emitting layer. A metal ion trapping layer is placed between the first electrode and the second electrode. The metal ion trapping layer is formed of a metal ion trapping material with a ring part including a plurality of Lewis basic elements bonded to at least two carbon atoms.
