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 light-emitting device is provided. The device includes a first electrode, a second electrode, an emission layer between the first electrode and the second electrode, a hole transport region between the first electrode and the emission layer, and an electron transport region between the emission layer and the second electrode. The hole transport region may include a hole transport layer, which in turn includes a first perovskite compound [A1l][B1m][X1]n with a neutral defect. A hole concentration of the first perovskite compound may be from about 1.0×1016 to about 9×1018 cm−3 at about 25° C.
