In order to provide an organic electroluminescent element which is able to emit light highly efficiently with high luminance, and which is suited to a longer service life, an organic electroluminescent element according to the present invention is provided with: a first light emitting unit (23) which is positioned on a negative electrode (21) side and comprises a first light emitting layer (28A); a second light emitting unit (24) which is adjacent to the first light emitting unit (23), with a first charge generation layer (26A) being interposed therebetween, and comprises a second light emitting layer (28B); and a third light emitting unit (25) which is adjacent to the second light emitting unit (24), with a second charge generation layer (26B) being interposed therebetween, and comprises a third light emitting layer (28C). The difference between the total thickness of the second light emitting unit (24) and the total thickness of the first light emitting unit (23), and the difference between the total thickness of the second light emitting unit (24) and the total thickness of the third light emitting unit (25) are 30-70 nm, respectively. |
