Title:
ORGANOELECTROLUMINESCENT DEVICE USING POLYCYCLIC AROMATIC COMPOUNDS
Document Type and Number:
WIPO Patent Application WO/2021/187924
Kind Code:
A1
Abstract:
An organoelectroluminescent device according to the present invention employs compounds of characteristic structures as a hole transport material and a dopant material in a hole injection layer or a hole transport layer, and in an emissive layer, respectively, and thus can be driven at a low voltage and realize highly efficient emission characteristics with excellent external quantum efficiency. Thus, the organoelectroluminescent device may be industrially advantageously used in a flat display device, a flexible display device, a single-color or white-color flat lighting device, a single-color or white-color flexible lighting device, and the like.
