Abstract:
An organic electroluminescent element having a structure in which a plurality of light-emitting layers stacked between a first electrode with light reflectivity and a second electrode with optical transparency while one or more interlayers with a light transmissive property are interposed between the plurality of light-emitting layers. A first interlayer is formed as the interlayer closest to the first electrode. A first light-emitting unit is formed between the first electrode and the first interlayer to include a first light-emitting layer which has a first light-emitting source, and a second light-emitting unit is formed on a side of the first interlayer close to the second electrode to include a second light-emitting layer which has a second light-emitting source. The first interlayer is a semi-transmissive layer which has both of optical transparency and light reflectivity and has a total light absorption ratio of 10% or less.
