Organic compound and organic electroluminescent element comprising same

The present invention relates to a novel organic compound, and an organic electroluminescent element having improved characteristics, such as luminous efficiency, driving voltage, and lifespan, by containing the novel organic compound in one or more organic material layers.

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

An organic light-emitting device includes a positive electrode, a negative electrode and at least one organic material layer between the positive electrode and the negative electrode. The at least one organic material layer includes a hole-injecting layer, a hole-transporting layer, an emission layer, an electron-transporting layer, and an electron-injecting layer, and the emission layer includes a host material and a dopant material. In addition, a lifetime enhancement layer including a bipolar compound is positioned between the emission layer and the electron-transporting layer.
