An organic light emitting display panel includes a light emitting diode array substrate and an encapsulation substrate adhered to the light emitting array diode substrate by an adhesive film. The light emitting array diode substrate includes a driving thin film transistor formed on a substrate, an organic light emitting diode including a first electrode connected to the driving thin film transistor, an organic emission layer formed on the first electrode, and a second electrode formed on the organic emission layer, and first and second passivation layers formed on the second electrode. In this regard, the first passivation layer is formed of an organic compound having at least one of the structural formulae described in Formula 1 below: 

Organic light emitting display panel and method of manufacturing the same

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.

An organic light emitting display device is provided to avoid color change due to a viewing direction. The organic light emitting display includes a light compensation layer having a refractive index different than that of an insulating layer. The organic light emitting display may be disposed at the side to which light emitted from an organic light emitting layer is entered to change the path and phase of light, thereby coinciding cavity peak phases for each wavelength of white light emitted from an organic light emitting unit.
