Provided are a display apparatus, which may be easily separated from a carrier substrate, and a method of manufacturing the same. The method of manufacturing a display apparatus includes: forming, on a carrier substrate, a first inorganic layer including silicon oxide; plasma-treating the first inorganic layer by using nitrous oxide gas; after the plasma-treating, forming a display substrate on the first inorganic layer; forming a display element layer above the display substrate; and separating the display substrate from the carrier substrate.
