Abstract
A P-type dopant is provided, which is a planar aromatic compound having different numbers of fluorine atoms and cyano groups connected at a periphery thereof, and allows adjustment of highest occupied molecular orbital (HOMO) energy levels and lowest unoccupied molecular orbital (LUMO) energy levels and effectively increases luminous efficiency of a light emitting layer. Moreover, an organic light emitting diode is disclosed, including an anode, a cathode, and a light emitting structure located between the anode and the cathode, wherein a hole injecting layer of the light emitting structure is a hole injecting layer including the P-type dopant described above.
