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 side of a light-emitting face. Further, the light-emitting device includes, on a side of the light-emitting face of the second electrode, a complementary color light absorption layer configured to absorb complementary color light of light emitted by the light-emitting element.
