摘要： The present invention provides a multicolor light-emitting device including a plurality of organic EL devices each having two or more different luminescent colors in which the take-out efficiency of the emission of each color can be optimized by a simple configuration and which has a low price and high efficiency. 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 having two or more different emission spectra, wherein light-emitting regions in the light-emitting layer of the organic EL devices each having the different emission spectra are located in different positions in the layer thickness direction corresponding to the different emission spectra, and allows the take-out efficiency of the light of the organic EL device for each color to be optimized while giving the same material, thickness and the like to the first charge-transporting layer 16, the second charge-transporting layer 13, the electrodes and the like.
