Abstract: A method of manufacturing a display device includes preparing an organic light-emitting device and forming an encapsulation member to encapsulate the organic light-emitting device. The forming of the encapsulation member includes forming a first inorganic encapsulation layer on the organic light-emitting device by providing a raw material gas on the organic light-emitting device, forming a first organic encapsulation layer by applying an organic material on the first inorganic encapsulation layer, and forming a second inorganic encapsulation layer on the first organic encapsulation layer. The raw material gas includes a nitrous oxide gas, a nitrogen gas, an ammonia gas, and a hydrogen gas, and a ratio of a sum of flow rates of the nitrous oxide gas and the nitrogen gas to a sum of flow rates of the ammonia gas and the hydrogen gas is about 1.1 or less.

Abstract: A display device includes a base layer, a circuit layer, a light emitting element layer, and a thin film encapsulation layer. The base layer includes a display area and a non-display area. The circuit layer includes a plurality of insulating layers, at least one of which has an opening. The light emitting element layer includes a light emitting area overlapping the display area, a valley area overlapping the opening and having a concave shape, and a peak area overlapping the non-display area and being on the circuit layer. The thin film encapsulation layer includes an organic encapsulation layer that covers the light emitting area, the valley area, and at least a portion of the peak area.
