Document Type and Number:
WIPO Patent Application WO/2018/124237
Kind Code:
A1
Abstract:
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.
