<p>Provided is a novel structure for an organic electroluminescent element which is capable of reducing a drive voltage, and which has a structure in which an insulating organic layer is disposed at a location that serves as a barrier to the movement of charges to a light-emitting layer, as a structure that allows electron charges to be moved in the direction of an anode, as viewed from a charge generation (carrier generation) location, and injected in the light-emitting layer, without using a strong electron-donating substance such as an alkali metal. The present invention pertains to an organic electroluminescent element characterized by having an anode, a cathode, a plurality of light-emitting units that includes a light-emitting layer and is positioned between the anode and the cathode, and intermediate layers that are positioned between the plurality of light-emitting units. The organic electroluminescent element is further characterized in that the intermediate layers each include an insulating organic layer that is disposed at a location that servers as a barrier to the movement of charges from the intermediate layer to the light-emitting unit, and a mixed layer comprising organic matter and a metal disposed adjacent to the insulating organic layer.</p> |
