Abstract
The light-emitting device includes: a base substrate; a light-emitting unit, disposed on the base substrate; and a thin film packaging structure disposed on a side, distal from the base substrate, of the light-emitting unit, wherein the thin film packaging structure includes a target packaging film layer of at least one packaging film layer is provided with a first packaging portion and a second packaging portion which are arranged in the same layer and are in contact with each other, an orthographic projection of the first packaging portion on the base substrate at least partially overlaps an orthographic projection of the light-emitting unit on the base substrate, an orthographic projection of the second packaging portion on the base substrate at least partially overlaps the orthographic projection of the light-emitting unit, and a refractive index of the first packaging portion is less than a refractive index of the second packaging portion.
