Claim:
1. An organic light-emitting device comprising: a first electrode; a second electrode; and an organic layer disposed between the first electrode and the second electrode, wherein the organic layer comprises a compound represented by Formula 1 and a compound represented by Formula 2: wherein, in Formula 1, R Ar is a lone pair of electrons, a substituted or unsubstituted C6-C60 aryl group, a substituted or unsubstituted C1-C60 heteroaryl group, or a substituted or unsubstituted C6-C60 condensed polycyclic group, and X is N (nitrogen) or S (sulfur), provided when X is N (nitrogen) then Ar is a substituted or unsubstituted C6-C60 aryl group, a substituted or unsubstituted C1-C60 heteroaryl group, or a substituted or unsubstituted C6-C60 condensed polycyclic group, and when X is S (sulfur) Ar is a lone pair of electrons, wherein, in Formula 2, L is a substituted or unsubstituted C6-C60 arylene group, or a substituted or unsubstituted C1-C60 heteroarylene group, R m is an integer of 0 to 5.
