Abstract
A display apparatus including a display substrate, light emitting devices disposed on the display substrate, circuit electrodes disposed between the light emitting devices and the display substrate, and a transparent layer covering the light emitting devices and the circuit electrodes, in which at least one of the light emitting devices includes a first LED sub-unit configured to emit light having a first wavelength, a second LED sub-unit adjacent to the first LED sub-unit and configured to emit light having a second wavelength, a third LED sub-unit adjacent to the second LED sub-unit and configured to emit light having a third wavelength, and a substrate disposed on the third LED sub-unit, in which a difference in refractive indices between the 10 transparent layer and air is less than a difference in refractive indices between the substrate and a semiconductor layer of the third LED sub-unit.
