ORGANIC ELECTROLUMINESCENT DEVICE

摘要

Disclosed is an organic electroluminescent device wherein an organic thin film composed of one or more layers is interposed between a cathode and an anode. In this organic EL device, a light-emitting layer contains a compound having a specific structure as a host material, while containing a metal complex compound having a specific structure including a central metal atom and a corresponding ligand as a dopant. This organic electroluminescent device is free from pixel defects, while having high luminance, high luminous efficiency and long life.
