摘要： This organic electroluminescent element comprises, between a negative electrode and a positive electrode, a plurality of light emitting units, each of which comprises at least a light emitting layer that is formed of an organic compound. With respect to this organic electroluminescent element, white light obtained by light emission of the plurality of light emitting units has an emission spectrum (S) that is continuous at least over a wavelength range of 380-780 nm. The emission spectrum (S) has one peak wavelength (p 1 ) in a red wavelength range (R) of 600-780 nm, one or two peak wavelengths (p x , p y ) in a green wavelength range (G) of 490-600 nm, and two peak wavelengths (p 2 , p 3 ) in a blue wavelength range (B) of 380-490 nm.
