A display device includes a substrate; a light-emitting element on the substrate; a capping layer on the light-emitting element; a first inorganic encapsulation layer on the capping layer; an organic encapsulation layer on the first inorganic encapsulation layer; and a second inorganic encapsulation layer on the organic encapsulation layer. The first inorganic encapsulation layer includes a first sub-inorganic encapsulation layer between the capping layer and the organic encapsulation layer, and a second sub-inorganic encapsulation layer between the first sub-inorganic encapsulation layer and the organic encapsulation layer.
