Abstract: A light emitting device and a display apparatus including a phase shifting mirror are provided. The light emitting device includes a first electrode, a light emitting structure, a second electrode, and a phase shifting mirror. The phase shifting mirror has a number of patterns arranged in a periodic manner with an interval between adjacent patterns. Each pattern has a top surface and a side surface between the top surface of the respective pattern and the top surface of the first electrode. A first width at a bottom portion of the respective pattern directly adjacent to the top surface of the first electrode is greater than a second width of the top surface of the respective pattern, and the first width and the second width are less than a wavelength of light generated in the light emitting structure.
