Beschreibung
Zusammenfassung:	An organoelectroluminescent device according to the present invention can achieve low-voltage driving and high-efficiency luminous characteristics with excellent external quantum efficiency by employing compounds having a characteristic structure as a hole transport material and a dopant material in a hole injection layer or hole transport layer and a light-emitting layer respectively, and thus can be effectively used in industrial applications such as flat display devices, flexible display devices, monochrome or white flat lighting devices, and monochrome or white flexible lighting devices.
