Abstract
An organic electroluminescent device including a substrate, an anode, a cathode, a hole transport layer, an electron transport layer and an emission layer is provided. The anode and the cathode are disposed on the substrate. The hole transport layer is disposed between the anode and the cathode. The electron transport layer is disposed between the hole transport layer and the cathode. The emission layer is disposed between the hole transport layer and the electron transport layer. The chemical structure of the dopant is represented by formula [I]: 'M' represents a metal atom, m is smaller than or equal to the ligand number of 'M', n is smaller than m. “Y1” is selected from aryl or heteroaryl. “Y2” and “Y3” are respectively selected from nitrogen-containing heterocyclic ring. “X”, “R1”, “R2” and “R3” are respectively selected from any substituent group or hydrogen. “A” is selected from aryl, heteroaryl or nitrogen-containing heterocyclic group.
