1. An organic light-emitting device, comprising:
a first electrode; a second electrode; an emission layer between the first electrode and the second electrode; a mixed organic layer between the emission layer and the first electrode, the mixed organic layer comprising: a fluorene derivative selected from Compound 5, Compound 6 and one of Formulas 2-9; and a pyrazine derivative represented by Formula 16: R, R1, R2, R3 and R4 in Formulas 1-9 being each independently one of a hydrogen atom, a substituted or unsubstituted C1-30 alkyl group, a substituted or unsubstituted C1-30 alkenyl group, a substituted or unsubstituted C1-30 alkoxy group, a substituted or unsubstituted C6-30 aryl group, a substituted or unsubstituted C6-30 aryloxy group, a substituted or unsubstituted C2-30 heteroaryl group, a substituted or unsubstituted C5-30 condensed polycyclic group, a hydroxyl group, a cyano group and a substituted or unsubstituted amino group, each R in Formula 16 being independently a hydrogen atom, a C1-C10 alkyl group, an alkyloxy group, dialkyl amine, halogen, or cyano; and an electron transport layer between the emission layer and the second electrode, the electron transport layer comprising a lithium quinolate and a pyridine derivative. |
