    摘要： Provided is an organic light emitting diode which can easily control color coordinates and improve a device's life span characteristic by using an auxiliary dopant having a higher band gap energy than that of a host, and preferably, having an absolute value of the highest occupied molecular orbital energy level equal to or higher than that of the host, or an absolute value of the lowest unoccupied molecular orbital energy level equal to or lower than that of the host. The organic light emitting diode includes a first electrode, an emission layer disposed on the first electrode and including a host, an emitting dopant and an auxiliary dopant, and a second electrode disposed on the emission layer. Here, the auxiliary dopant has a higher band gap energy than the host. A method of fabricating the organic light emitting diode is provided.
