Abstract:
1. A light-emitting device comprising: a first element comprising: a second element comprising: wherein a first optical path length is an optical path length between the first electrode and the first light-emitting layer, and the first optical path length is determined based on a first wavelength range in which the first color filter layer has a transmittance of 50% or higher in the visible light range, wherein a second optical path length is an optical path length between the second electrode and the second light-emitting layer, and the second optical path length is determined based on a second wavelength range in which the second color filter layer has a transmittance of 50% or higher in the visible light range, and wherein a wavelength of a color of light emitted from the first light-emitting layer is longer than a wavelength of a color of light emitted from the second light-emitting layer.
