Abstract: Disclosed is a combination of host materials of a red light-emitting layer that can lower an operation voltage of an organic light-emitting diode, and improve light-emitting efficiency and lifetime thereof. In addition, disclosed is a charge scavenger which causes quenching with polaron to reduce triplet polaron quenching (TPQ) and roll-off occurring in the organic light-emitting diode. Further, disclosed is an organic light-emitting diode including the charge scavenger.
