1. An organic light-emitting device, comprising:
a pair of electrodes; and an organic compound layer placed between the pair of electrodes, wherein the organic compound layer comprises an iridium complex represented by the following general formula [1] and a metal complex represented by the following general formula [5]: in the formula [1]: m represents an integer of 1 to 3, and n represents an integer of 0 to 2, provided that a relationship of m+n=3 is satisfied; R1 to R14 each represent a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, a substituted amino group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group, and may be identical to or different from one another, provided that when m represents 3 or when X is free of an alkyl group, at least one of substituents represented by R1 to R14 comprises an alkyl group; X represents a bidentate ligand; and a partial structure IrXn represents any one of partial structures represented by the following general formulae [2] to [4]: in the formulae [2] to [4], R15 to R29 each represent a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, a substituted amino group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group, and may be identical to or different from one another, provided that when none of R1 to R14 represents an alkyl group, at least one of substituents represented by R15 to R29 comprises an alkyl group, and when n represents 2, multiple substituents represented by any one of R15 to R29 may be identical to or different from each other;
ML2 [5] in the formula [5]: M represents a divalent metal atom selected from beryllium, magnesium, and zinc; L represents a bidentate ligand; when M represents beryllium or magnesium, a partial structure ML comprises any one of structures represented by the following general formulae [6] to [11]; and when M represents zinc, the partial structure ML comprises any one of structures represented by the following general formulae [7] to [11]: in the formulae [6] to [11], R30 to R57 each represent a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, an alkoxy group, a substituted amino group, a substituted or unsubstituted aromatic hydrocarbon group, or a substituted or unsubstituted heteroaromatic group, and in the formulae [8] to [11], a ring B comprises any one of cyclic structures represented by the following general formulae [12] to [14], *1 represents a bonding position with an oxygen atom, and *2 represents a bonding position with a carbon atom in a five-membered heterocyclic skeleton: in the formulae [12] to [14], R58 to R71 each represent a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, an alkoxy group, a substituted amino group, a substituted or unsubstituted aromatic hydrocarbon group, or a substituted or unsubstituted heteroaromatic group. |
