1. A light-emitting device comprising:
a reflective layer;
a first electrode provided on the reflective layer;
a second electrode facing the first electrode;
a phase correction layer provided between the first electrode and the second 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, the first partial transmission mirror being in direct contact with a surface of the phase correction layer,
wherein the first emission layer and the second emission layer generate light in a wavelength range of same color.
