Multicolor light-emitting device

摘要

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.
