摘要： A light-emitting device and an electronic apparatus including the same are provided. The light-emitting device includes a first electrode, a second electrode facing the first electrode, an interlayer between the first electrode and the second electrode and including an emission layer, and a capping layer. The emission layer includes a first emitter, the first emitter emits first light having a first emission spectrum, the capping layer is in the path on which the first light travels, an emission peak wavelength of the first light is from about 520 nm to about 550 nm. The first emitter includes iridium, the capping layer includes an amine-containing compound, and the value of ratio of CIEy to reflective index (RCR value) of the first light extracted to the outside through the capping layer is 38 or less, and the RCR value is calculated according to
CIEy/R(cap)×100.-
