Abstract:
An organic electroluminescent element in accordance with the present invention includes: a transparent electrode; a blue light-emitting layer containing a blue light-emitting material having a maximum emission wavelength 460 nm or less; a first green light-emitting layer containing a first green light-emitting material having a maximum emission wavelength in the spectrum between 460 nm and 610 nm; a red light-emitting layer containing a red light-emitting material having a maximum emission wavelength of 610 nm or more; a second green light-emitting layer containing a second green light-emitting material having a maximum emission wavelength in the spectrum between 460 nm and 610 nm; and a reflecting electrode. The maximum emission wavelength of the first green light-emitting material is located on a short wavelength side of the spectrum. The maximum emission wavelength of the second green light-emitting material is located on a long wavelength side of the spectrum.
