ABSTRACT:
The present invention provides an organic electroluminescence device, by which high brightness is provided in a manner of forming a hole injection or transport layer using a material that lowers an energy barrier. The present invention includes an organic emitting layer between a cathode and an anode and a hole injection and/or transport layer between the anode and the organic emitting layer, wherein at least one of the hole injection and transport layers has a configuration of Formula 1,wherein each of the R1 to R8 is selected from an independently substituted or non-substituted aromatic group, a heterocyclic group, an aliphatic group and hydrogen.
