Abstract:
The organic electroluminescence device has, on a substrate thereof, a pair of electrodes and at least one organic layer including a light emitting layer between the electrodes, wherein the light emitting layer contains a phosphorescent complex material containing a specific monoanionic bidentate ligand and the device contains, in a layer sandwiched between the light emitting layer and a cathode, a compound represented by the following formula (1): (Cz)p-L-(A)q (1) wherein, Cz represents a substituted or unsubstituted arylcarbazolyl or carbazolylaryl, L represents a single bond or a substituted or unsubstituted arylene, cycloalkylene, or aromatic heterocycle, A represents a substituted or unsubstituted nitrogen-containing 6-membered aromatic heterocycle, and each of p and q independently represents an integer from 1 to 6.
