Abstract
A light emitting device including a micro cavity having a phase modulation surface and a display apparatus including the light emitting device are provided. The light emitting device includes a reflective layer including a phase modulation surface; a first electrode disposed on the phase modulation surface of the reflective layer; a light emitting structure disposed on the first electrode; and a second electrode disposed on the light emitting structure. The phase modulation surface may include a plurality of nano scale patterns that are regularly or irregularly arranged. The reflective layer and the second electrode may constitute the micro cavity having a resonance wavelength of the light emitting device.
