1. A light-emitting device comprising:
a light-emitting face;
a plurality of light-emitting elements in each of which a first electrode, a light-emitting layer, and a second electrode are sequentially layered toward a side of the light-emitting face,
wherein each of the plurality of light-emitting elements includes a first light-emitting element configured to emit a first color light, a second light-emitting element configured to emit a second color light being different in color from the first color light, and a third light-emitting element configured to emit a third color light being different in color from the first color light and the second color light;
on the side of the light-emitting face of each of the plurality of light-emitting elements, a complementary color light absorption layer configured to absorb complementary color light of light emitted by each of the plurality of light-emitting elements; and
a sealing layer provided on the side of the light-emitting face of the complementary color light absorption layer, wherein
the complementary color light absorption layer includes, in a plane view, a first complementary color light absorption layer configured to absorb complementary color light of the first color light at a position where the complementary color light absorption layer is superimposed on the first light-emitting element, a second complementary color light absorption layer configured to absorb complementary color light of the second color light at a position where the complementary color light absorption layer is superimposed on the second light-emitting element, and a third complementary color light absorption layer configured to absorb complementary color light of the third color light at a position where the complementary color light absorption layer is superimposed on the third light-emitting element.
