摘要： Provided is an organic electroluminescence device that can be driven at a low voltage, and has a high efficiency, excellent durability and a small change in chromaticity when driving at a high temperature. The organic electroluminescence device has a pair of electrodes disposed on a substrate and at least one organic layer including a light emitting layer disposed between the electrodes. The organic electroluminescence device contains a compound represented by the following Formula (1) in any one layer of the organic layers and a phosphorescence emitting material represented by the following Formula (C-1) in the light emitting layer.

         (Cz)p-L-(A)q     (1)


In Formula (1), Cz is a substituted or unsubstituted arylcarbazolyl group or a carbazolylaryl group, L is a single bond or a substituted or unsubstituted arylene group, a substituted or unsubstituted cycloalkylene group, or a substituted or unsubstituted aromatic heterocyclic ring, A is a substituted or unsubstituted nitrogen-containing six-membered aromatic heterocyclic ring, and each of p and q is independently an integer of 1 to 6.

In Formula (C-1), each of Q1, Q2, Q3 and Q4 independently represents a ligand which is coordinated to Pt. Each of L1, L2 and L3 independently represents a single bond or a divalent linking group.
