LIGHT-EMITTING DEVICE, ELECTRONIC DEVICE INCLUDING THE SAME, AND ELECTRONIC APPARATUS INCLUDING THE SAME

Embodiments provide a light-emitting device, an electronic device including the same, and an electronic apparatus including the light-emitting device. The light-emitting device includes a first electrode, a second electrode facing the first electrode, and an interlayer between the first electrode and the second electrode. The interlayer includes a hole transport region and an emission layer; the hole transport region is disposed between the first electrode and the emission layer; the hole transport region includes a first layer, which directly contacts the emission layer; the emission layer includes a first host and a first emitter; the first emitter emits first light having a first emission spectrum; and the first layer includes a first material.
