Abstract:
Disclosed are a tandem white organic light emitting diode with long lifespan and low driving voltage, and a display device including the same. The white organic light emitting diode includes a first light emitting part, a second light emitting part and a third light emitting part disposed between a first electrode and a second electrode. The first and third light emitting parts include a blue light emitting layer and the second light emitting part includes a red light emitting layer and a yellow-green light emitting layer. At least one layer of the red light emitting layer and the yellow-green light emitting layer includes a hole transport host based on a compound shown below: wherein each of R1, R2, and R3 are independently selected from hydrogen, heavy hydrogen, a C5-C7 aromatic cyclic and C1-C6 heterocyclic group.
