ORGANIC ELECTROLUMINESCENT DEVICE, METHOD FOR MANUFACTURING THE SAME, SURFACE LIGHT SOURCE, ILLUMINATING DEVICE AND DISPLAY DEVICE

摘要

An organic electroluminescent element comprising:
an anode;
a cathode; and
a light emitting unit arranged between the anode and the cathode and having three or more light emitting layers each containing a polymer compound, wherein
the light emitting layers constituting the light emitting unit emit lights differing from each other in peak wavelength, and a light emitting layer that emits a light with a longer peak wavelength is located closer to the anode.
