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.
