Abstract: A method of manufacturing a display device includes forming a light emitting structure on a substrate and forming a thin film encapsulation layer on the light emitting structure by chemical vapor deposition equipment. The forming the thin film encapsulation layer includes forming a first inorganic layer and performing a first plasma treatment on a first portion of the first inorganic layer which is opposite to a second portion of the first inorganic layer facing the light emitting structure. A first raw material in the forming the first inorganic layer includes hydrogen. A second raw material in the performing the first plasma treatment exclusively consists of hydrogen.
