摘要： Provided is an organic electroluminescent element that can obtain white light with excellent color rendering properties and is particularly suitable for a light source of a lighting device. The organic electroluminescent element includes a plurality of light emitting units that are provided between a cathode and an anode and include at least a light emitting layer made of an organic compound. White light emitted from the plurality of light emitting units has a continuous emission spectrum (S) in a wavelength range of at least 380 nm to 780 nm. The emission spectrum (S) includes one peak wavelength (p1) in a red wavelength range (R) of 600 nm to 640 nm, one peak wavelength (p2) in a green wavelength range G of 500 nm to 540 nm, and two peak wavelengths (p3) and (pa) in a blue wavelength range B of 440 nm to 490 nm.

摘要： This organic electroluminescent element has a structure in which, between a first electrode and a second electrode, a plurality of light-emitting units are layered with a charge generation layer 14 interposed therebetween, and comprises a red light-emitting unit and a green light-emitting unit. In the organic electroluminescent element, yellow or orange light obtained by light emission from the two light-emitting units has a peak wavelength in each of a red wavelength range of 590-640 nm and a green wavelength range of 500-560 nm, and the difference between the peak wavelength of the yellow or orange light and the dominant wavelength of the yellow or orange light is 15-25 nm.
