This invention relates to novel organic electroluminescent compounds and organic electroluminescent devices containing them. The organic electroluminescent compounds according to the present invention have the advantage of reducing the driving voltage of the device and improving the power efficiency, thus enabling the manufacture of OLED devices.
The present disclosure relates to an organic electroluminescent device comprising a light-emitting layer and a hole transport zone. By comprising a specific combination of a light-emitting layer and a hole transport zone, it is possible to provide an organic electroluminescent device having low driving voltage, high luminous efficiency and/or long lifespan properties.
