    摘要： The present invention relates to a white organic light emitting device and a method for manufacturing the same, in which a hole transport layer is made to have an energy level higher than an energy level of an excited state of a phosphorescent light emitting layer adjacent thereto for enhancing light emitting efficiency of the hole transport layer without an additional exciton blocking layer, and a dopant content in the phosphorescent light emitting layer is adjusted for preventing color shift from taking place.The white organic light emitting device includes an anode and a cathode placed on a substrate opposite to each other, a charge generation layer formed between the anode and the cathode, a first stack of a first hole transport layer, a first light emitting layer for emitting a blue light, and a first electron transport layer between the anode and the charge generation layer, and a second stack of a second hole transport layer, a second light emitting layer having a host doped with phosphorescence red and green together, and a second electron transport layer between the charge generation layer and the cathode, wherein the second hole transport layer has an energy level set higher than a triplet excited state energy level of the second light emitting layer.
