An organic light emitting diode includes an anode, an emission layer disposed on the anode and including a host, a phosphorescent dopant represented by Chemical Formula 1 and a fluorescent dopant represented by Chemical Formula 2, and a cathode disposed on the emission layer formed by mixing the fluorescent dopant with the phosphorescent dopant including an acceptor at a specific site, thereby energy loss during an emission process can be minimized and energy transfer efficiency can be improved and an organic light emitting diode with excellent luminous efficiency and an organic light emitting display device having the same can be achieved.
