Original Abstract Submitted
a light emitting device may include a first electrode, a first light emitting stack disposed on the first electrode, a charge generation layer disposed on the first light emitting stack, a second light emitting stack disposed on the charge generation layer, and a second electrode disposed on the second light emitting stack. each of the first light emitting stack and the second light emitting stack includes a hole transport layer. a hole mobility of the charge generation layer is lower than a hole mobility of the hole transport layer.
