Abstract
Provided are a light-emitting device and a manufacturing method thereof, and a display device, and relates to the field of display technology. The light-emitting device includes: a light-emitting unit located on one side of a backplane; and an encapsulation layer located on one side of the light-emitting unit away from the backplane. The encapsulation layer includes: a first inorganic layer; a second inorganic layer located on one side of the first inorganic layer away from the backplane; an organic layer located between the first inorganic layer and the second inorganic layer; and a third inorganic layer located between the first inorganic layer and the organic layer. The refractive index of the first inorganic layer, the refractive index of the third inorganic layer, and the refractive index of the organic layer decrease sequentially.
