The present disclosure relates to a novel organic compound and an organic electroluminescent device comprising the same, and the organic compound of the present disclosure may be used for an organic material layer of the organic electroluminescent device, thereby improving the light emitting efficiency, driving voltage, lifetime, and the like of the organic electroluminescent device.

Organic compound and organic electroluminescent device comprising the same

An organic light-emitting device includes: a first electrode; a second electrode opposite the first electrode; an emission layer between the first electrode and the second electrode; a hole transport region between the first electrode and the emission layer; and an electron transport region between the emission layer and the second electrode, the electron transport region including an electron control layer, wherein the hole transport region includes at least one compound selected from a first compound represented by Formula 1 and a second compound represented by Formula 2, and the electron control layer includes a third compound represented by Formula 3: 

Organic light-emitting device

The present invention provides an organic electroluminescent element which comprises: an anode; a cathode; and an organic layer interposed between the anode and the cathodes, wherein the organic layer comprises one or more types of layer from the group consisting of a hole-injection layer, hole-transport layer, light-emitting layer, lifetime enhancement layer, electron-transport layer, and electron-injection layer.

Organic electroluminescent element

Provided is a white light emitting organic electroluminescent device, which includes a transparent substrate, a first element, and a second element, wherein the first element includes a first anode, a first element organic layer, and a reflective cathode sequentially disposed on a first substrate of the transparent substrate, and wherein the second element includes a second anode, a second element organic layer, and a transparent or translucent cathode sequentially disposed on a second surface of the transparent substrate.
