Light emitting device and display apparatus including the same

A display apparatus comprising:

• a first pixel configured to emit light of a first wavelength;
• and
• a second pixel configured to emit light of a second wavelength different from the first wavelength,
• the first pixel comprises:
• a reflective layer comprising a phase modulation surface;
• a planarization layer disposed on the reflective layer;
• a first electrode disposed on the planarization layer;
• an organic emission layer disposed on the first electrode and configured to emit visible light that comprises the light of the first wavelength and the light of the second wavelength that is shorter than the first wavelength;
• and
• a second electrode disposed on the organic emission layer,
• wherein the reflective layer and the second electrode form a micro cavity configured to resonate the light of the first wavelength, and
• wherein the planarization layer comprises a light absorber configured to absorb the light of the second wavelength.
