Abstract
To provide an organic electroluminescent element having a low driving voltage, high current efficiency and high voltage efficiency.An organic electroluminescent element comprising an anode, a cathode and an organic layer disposed between the anode and the cathode, wherein the organic layer comprises a mixed layer containing a light-emitting low molecular compound and/or a charge-transporting low molecular compound in a film containing an insolubilized polymer obtained by insolubilizing an insolubilizing polymer, and, adjacent to the mixed layer, a layer containing a light-emitting low molecular compound and a charge-transporting low molecular compound and not containing an insolubilized polymer.
