By doping the cerium salt having a low work function into the hole transportation material as the electron barrier layer, the LUMO energy level of the hole transportation material is greatly increased, thereby elevating the potential barrier between the electron barrier layer and the light-emitting layer, so that it is difficult for the electrons to transit to the side of the hole transportation layer and a good electron barrier effect is achieved.
