  • LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE SAME
    Publication number: 20220165957
    Abstract: A 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 an emission layer. The interlayer further includes a first electron transport layer and a second electron transport layer. The first and second electron transport layers are between the emission layer and the second electrode. The first electron transport layer includes a first compound represented by Formula 1, and the second electron transport layer includes a second compound represented by Formula 2.
