Abstract
A light-emitting device includes a first electrode, a second electrode facing the first electrode, an interlayer disposed between the first electrode and the second electrode and including an emission layer, a first capping layer, and a second capping layer. A refractive index of the first capping layer is greater than a refractive index of the second capping layer, and the first capping layer and the second capping layer are each an organic layer. An electronic apparatus including the light-emitting device is also provided.
