A display apparatus includes a base substrate, a light emitting structure disposed on the base substrate, and a thin film encapsulation layer disposed on the light emitting structure and including at least one inorganic layer and at least one organic layer. The at least one inorganic layer includes a high density layer having a density of greater than or equal to about 2.0 g/cm3 and a low density layer having a density of less than about 2.0 g/cm3. The high density layer and the low density layer are in contact with each other.
