Abstract: An organometallic compound represented by Formula 1:




wherein, in Formula 1, M1 is a transition metal, L1 is a ligand represented by Formula 1A, L2 is a ligand represented by Formula 1B, and n1 and n2 are each independently 1 or 2,




wherein X1 is C or N; X2 is C or N; ring CY1 and ring Lio are each independently a C5-C30 carbocyclic group or a C1-C30 heterocyclic group; X21 is C(R21) or N; X22 is C(R22) or N; X23 is C(R23) or N; X24 is C(R24) or N; * and *′ each indicate a binding site to M1; R21 and R22, R22 and R23, or R23 and R24 are bonded to each other to form a substituted or unsubstituted C5-C30 carbocyclic group or a substituted or unsubstituted C1-C30 heterocyclic group; and the remaining substituent groups are as defined herein.
