Discussed is an organic light emitting device that exhibits improved efficiency and driving voltage by applying a novel material facilitating charge generation to a charge generation layer. The charge generation layer contains a compound represented by the following formulae: wherein R1, R2, R3, R4, R5, R6, R7 and R8 are optionally substituted and are independently selected from an aromatic group having 6 to 20 carbon atoms, and R9 and R10 are independently selected from hydrogen, an optionally substituted aromatic ring having 6 to 20 carbon atoms and an optionally substituted heterocyclic compound having 3 to 17 carbon atoms and one or more elements of N, S and P.

Organic light emitting device

According to the present invention, there is provided a white organic light emitting diode (W-OLED) display device for effectively blocking outgas generated from a color filter using silicon nitride having a low water vapor transmission rate as a passivation layer instead of a planarization layer which is an organic insulating layer, and a method of fabricating the same.
