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,

Claims (3)

1. An organic electroluminescence device comprising:

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,
