Abstract: 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.

Abstract: A display apparatus includes a substrate. A first buffer layer is disposed over the substrate. The first buffer layer includes silicon nitride and has an atomic percentage of hydrogen bonded to silicon of about 0.36 to about 1.01. A thin film transistor is disposed over the first buffer layer. The thin film transistor includes an active layer. A display element is electrically connected to the thin film transistor.
