Abstract: A display device includes: a substrate; an organic light-emitting diode positioned above the substrate; and a thin film encapsulation layer disposed on the organic light-emitting diode. The thin film encapsulation layer includes: at least one inorganic layer; and at least one organic layer disposed on the at least one inorganic layer. The at least one organic layer has a refractive index of about 1.66 or greater.

Abstract: A light-emitting device is provided. The light emitting device includes a first electrode, second electrode facing the first electrode, and an emission layer between the first electrode and the second electrode. The emission layer includes at least one perovskite compound, a first quantum dot, and a second quantum dot. The first quantum dot and the second quantum dot may be different from each other.
