Abstract

A light-emitting device and an electronic apparatus including the same are disclosed. The light-emitting device, includes: a first electrode; a second electrode facing the first electrode; and an interlayer arranged between the first electrode and the second electrode, wherein the interlayer includes a first emission layer and a second emission layer, the first emission layer includes a first compound that emits a first light having a first spectrum, the second emission layer includes a second compound that emits a second light having a second spectrum, the first compound includes a first transition metal, the second compound includes a second transition metal, the first transition metal and the second transition metal are different from each other, |HOMO(1) - HOMO(2)| is about 0.05 eV to about 0.4 eV, and |λmax(1) - λmax(2)| is about 0 nm to about 30 nm, wherein HOMO(1), HOMO(2), λmax(1), and λmax(2) are as described herein.
