A pyrene compound and an organic light emitting diode device including the same are disclosed. The organic light emitting diode device includes at least two stacks provided between a first electrode and a second electrode, and a charge generation layer provided between the stacks and including an N type charge generation layer and a P type charge generation layer, wherein the N type charge generation layer is made of the pyrene compound.

Pyrene compound and organic light emitting diode device including the same

An organic light emitting diode device is disclosed. There is an organic light emitting diode device that comprises a first light emitting part between an anode and a cathode, the first light emitting part including a first light emitting layer, a second light emitting part comprising a second light emitting layer on the first light emitting part, and a first charge generation layer between the first light emitting part and the second light emitting part, wherein the first charge generation layer comprises at least two hosts, and at least one of the at least two hosts includes a pyrene compound.

Organic light emitting diode device

Provided is a white organic light emitting diode device, including first and second electrodes facing each other above a substrate, first and second charge generation layers formed between the first electrode and the second electrode, a first stack disposed between the first electrode and the first charge generation layer and including a first light emitting layer, a second stack disposed between the first charge generation layer and the second charge generation layer and including a second light emitting layer, and a third stack disposed between the second charge generation layer and the second electrode and including a third light emitting layer, wherein two of the first to third light emitting layers emit a blue light and the rest light emitting layer emits a yellow-green light.
