Patent ID: 10050237

Abstract:
An object of the present invention is to provide an organic electroluminescent element containing: a plurality of light emitting units interposed between a pair of an anode and a cathode; and a charge generating unit formed between the light emitting units, wherein a light emitting layer of a light emitting unit located in an N-th order from the anode and a light emitting layer of a light emitting unit located in an (N+1)-th order from the anode each contain an emission dopant to emit light of the same emission color; and a largest maximum emission wavelength in a photoluminescent spectrum of the emission dopant in the light emitting layer of the N-th light emitting unit is shorter than a largest maximum emission wavelength in a photoluminescent spectrum of the emission dopant in the light emitting layer of the (N+1)-th light emitting unit.
