1. A display apparatus, comprising:
a substrate including a first surface and a second surface opposing each other;
a light shielding layer covering the second surface of the substrate;
a plurality of nitride semiconductor layers directly disposed on the first surface of the substrate and defining a light emitting area; and
a plurality of pads disposed on the nitride semiconductor layers,
wherein the light shielding layer has a thickness greater than a length of a longest wavelength among wavelengths of light generated from the light emitting area, and
wherein an upper surface of the light shielding layer is curved along a direction from the second surface to the first surface, and the thickness of the light shielding layer varies.
