Zusammenfassung: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, wherein the interlayer includes an emission layer, a hole transport layer, and an electron transport layer. The emission layer includes an electron transport host compound and a dopant. A hole mobility of the hole transport layer is greater than 1×10−4 cm2/Vs, an electron mobility of the electron transport layer is greater than 1×10−5 cm2/Vs, and an electron mobility of the electron transport host compound is less than 1×10−8 cm2/Vs.
