Abstract:
1. An electroluminescent device comprising: a first and a second optical output parts operable to emit light, wherein a first emission peak wavelength represents a wavelength at which an emission spectrum of the light from the first optical output part reaches a first maximum intensity value, and a second emission peak wavelength represents a wavelength at which an emission spectrum of the light from the second optical output part reaches a second maximum intensity value, wherein the visibility spectrum curve comprises a first inclination value at the first emission peak wavelength, and a second inclination value at the second emission peak wavelength, both of the first and the second inclination values being greater than zero, and the second inclination value being greater than the first inclination value, and wherein a second width of the emission spectrum of the second optical output part is broader than a first width of the emission spectrum of the first optical output part.
