1. A method of manufacturing a display apparatus comprising:
performing a first repair process of detecting a first defective light emitting diode (LED) provided on a sapphire substrate and removing the first defective LED so that a first plurality of LEDs remain on the sapphire substrate;
attaching the first plurality of LEDs to electrode patterns of an interposer substrate and separating the sapphire substrate from the first plurality of LEDs; and
performing a second repair process of detecting a second defective LED among the first plurality of LEDs that have been separated from the sapphire substrate and are attached to the electrode patterns, and replacing the second defective LED with a second repair LED so that a second plurality of LEDs are provided on the interposer substrate, wherein the second repair LED is one of the second plurality of LEDs.
