Abstract
A light-emitting device includes a first electrode, a second electrode facing the first electrode, and an interlayer disposed between the first electrode and the second electrode. The interlayer includes an emission layer, and a distributed Bragg reflector (DBR) layer in which a first layer and a second layer are alternately stacked. A refractive index of the first layer is different from a refractive index of the second layer.
