Patent ID: 8564190

Claim:
A light-emitting element comprising: an anode; a cathode; and a first light-emitting layer, a second light-emitting layer, a third light-emitting layer, a first intermediate layer, and a second intermediate layer between the anode and the cathode, wherein the first intermediate layer is provided between the first light-emitting layer and the second light-emitting layer, wherein the second intermediate layer is provided between the second light-emitting layer and the third light-emitting layer, wherein a spectrum of light emitted from each of two of the first to third light-emitting layers has a peak in a yellow to orange wavelength range, wherein an emission spectrum obtained by combining the spectra of light emitted from the two of the first to third light-emitting layers has a peak of which a wavelength is greater than or equal to 560 nm and less than 580 nm, and wherein a spectrum of light emitted from the other of the first to third light-emitting layers has a peak in a blue wavelength range.
