Abstract: An organometallic compound represented by Formula 1:

        Formula 1     Ml(Ll)nl(L2)n2

wherein Mi is a transition metal, Li is a ligand represented by Formula 1A, L 2 is a ligand represented by Formula 1B, and n1 and n2 are each independently 1 or 2,


with the proviso that i) X 45 is C(R 45 ), X 46 is C(R 46 ), and R 45 and R 46 are bonded to each other to form a group represented by Formula 2, ii) X 46 is C(R 46 ), X 47 is C(R 47 ), and R 46 and R 47 are bonded to each other to form a group represented by Formula 2, or iii) X 47 is C(R 47 ), X 48 is C(R 48 ), and R 47 and R 48 are bonded to each other to form a group represented by Formula 2, ring CY 42 and ring CYs are condensed with each other, and the remaining substituent groups are as defined herein.
