摘要： A white organic light-emitting device is provided by the present invention. The white organic light-emitting device includes an anode, a hole transport layer, a first light-emitting layer, a second light-emitting layer, a third light-emitting layer, an electron transport layer and a cathode, wherein the second light-emitting layer is formed between the first and the third light-emitting layers, the emission wavelength of the second light-emitting layer is longer than that of the first and third light-emitting layers, and the host material of the first and third light-emitting layer are different. The white organic light-emitting device of the present invention is capable of effectively increasing the luminous efficiency, reducing operating voltage, and providing color stability.
