A multicolor light-emitting device includes a plurality of organic EL
devices each having two or more different luminescent colors. The
multicolor light-emitting device includes a plurality of organic EL
devices each having an organic compound layer including a light-emitting
layer 12 between a reflecting electrode 11 and a transparent electrode
14. The plurality of organic EL devices each has two or more different
emission spectra, wherein light-emitting regions in the light-emitting
layer of the organic EL devices each having different emission spectra
are located in different positions in the layer thickness direction
corresponding to the different emission spectra.
