ABSTRACT:
To provide an electroluminescent device excellent in color rendition, the electroluminescent device has at least two luminescent local maxima in a visible range, the at least two luminescent local maxima including a first luminescent local maximum and a second luminescent local maximum, the first and second luminescent local maxima have the two largest values of the at least two luminescent local maxima, wherein the electroluminescent device has the first luminescent local maximum in a range of from 450 to 530 nm, and the electroluminescent device has the second local luminescent local maximum in a range of 605 nm or more.
