Abstract:
A light-emitting device includes: a reflective layer; a first electrode provided on the reflective layer; a second electrode facing the first electrode; a first emission layer provided between the first electrode and the second electrode; a second emission layer provided between the first emission layer and the second electrode, and a first partial transmission mirror provided between the first emission layer and the second emission layer so that a first or higher order resonance mode is formed between the reflective layer and the first partial transmission mirror, and a second or higher order resonance mode is formed between the reflective layer and the second electrode.
