ABSTRACT:
An organic electroluminescent device having a pair of electrodes and at least one organic layer including a light-emitting layer interposed between the pair of electrodes, in which the organic layer contains at least one platinum complex compound having a quadridentate ligand containing a partial structure represented by formula (I):wherein Z1represents a nitrogen-containing heterocycle coordinated to the platinum through a nitrogen atom; L1represents a single bond or a linking group; R1, R3and R4each independently represent a hydrogen atom or a substituent; and R2represents a substituent.
