Zusammenfassung:An organic electroluminescent element includes constituent layers including at least one light-emitting layer. At least one layer of the constituent layers includes a hexa-coordinated ortho-metalated iridium complex represented by the following general formula (1) In the general formula (1), R 1 represents an alkyl group; the total carbon number of (R 1 ) k on the ring A is five or less; R 2 and R 3 each represents a substituent group; n represents an integer from 1 to 3; k represents n integer from 1 to 3; j and m each represents an integer from 0 to 4; and L represents a monoanionic bidentate ligand having coordinate covalent bonds to Ir.
