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:wherein R1, R2, R3, R4, R5, and R6 are each independently selected from substituted or unsubstituted C6-C40 aromatic groups.
