Abstract
The light-emitting device includes a light-emitting element in which a first electrode, a light-emitting layer, and a second electrode are sequentially layered toward a light-emitting face side. The plurality of light-emitting elements include a first light-emitting element configured to emit light of a first color, a second light-emitting element configured to emit light of a second color different from the first color, and a third light-emitting element configured to emit light of a third color different from the first color and the second color. The light-emitting device includes a light absorption layer on the light-emitting face side of the second electrode, in plane view, in common at positions where the light absorption layer is superimposed on the plurality of light-emitting elements, and the light absorption layer absorbs the light of the first color, the light of the second color, and the light of the third color.
