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 emission layer includes a first emission layer and a second emission layer. The first emission layer includes a first compound, and the second emission layer includes a second compound. The first compound includes at least one deuterium (D), and the second compound does not include deuterium. An electronic apparatus including the light-emitting device is also provided.

Abstract: A light-emitting device includes a first emission layer and a second emission layer, wherein the first emission layer includes a first hole-transporting host (HTH1), a first electron-transporting host (ETH1), and a first phosphorescent dopant (G1), and the second emission layer includes a second hole-transporting host (HTH2), a second electron-transporting host (ETH2), and a second phosphorescent dopant (G2). The electron mobility of the ETH1 is faster than the electron mobility of the ETH2, the hole mobility of the HTH2 is faster than the hole mobility of the HTH1, and the HTH1 and/or HTH2 includes deuterium.
