Abstract: An organic light-emitting diode display includes an organic light-emitting display device including a first electrode, an intermediate layer including an organic emission layer, and a second electrode; a first inorganic encapsulation layer on the second electrode; a second inorganic encapsulation layer on the first inorganic encapsulation layer; and an organic encapsulation layer on the second inorganic encapsulation layer. A refractive index of the first inorganic encapsulation layer is higher than a refractive index of the second inorganic encapsulation layer. The first inorganic encapsulation layer has an extinction coefficient of 0.02 to 0.07 and a refractive index of 2.1 to 2.3 at a blue wavelength.

Abstract: A display device includes a substrate and a light emitting layer on the substrate. The display device further includes a sealing portion on the light emitting layer. The sealing portion comprises a first inorganic layer. The first inorganic layer comprises at least one layer including silicon, oxygen, nitrogen and hydrogen. The at least one layer of the first inorganic layer includes a content of silicon of about 30-40 (at %), a content of oxygen of about 15-35 at %, a content of nitrogen of about 10-20 at %, a content of hydrogen of about 20-30 at %.
