摘要： Disclosed is a display apparatus comprising a plurality of pixels and a light emitting device on each of the plurality of pixels. The light emitting device includes a first semiconductor layer, an active layer, and a second semiconductor layer that are sequentially stacked on a bottom surface and a sidewall of the light emitting device. The sidewall of the light emitting device includes a first facet and a second facet adjacent to the first facet. A first angle is made between the bottom surface and the first facet. A second angle is made between the bottom surface and the second facet. The first facet and the second facet meet each other to define an edge. The edge extends from the bottom surface toward a top surface of the light emitting device.
