    Abstract: A light emitting device including a first electrode and a second electrode, and an emission layer disposed between the first electrode and the second electrode and including quantum dots, a first charge auxiliary layer disposed between the emission layer and the first electrode, and a second charge auxiliary layer disposed between the emission layer and the second electrode, wherein the emission layer comprises a first emission layer contacting the first charge auxiliary layer, a second emission layer disposed on the first emission layer, and a third emission layer disposed on the second emission layer. The hole mobility of the first emission layer decreases sequentially from the first emission layer to the third emission layer.
