Abstract: Discussed is a method of manufacturing an organic light emitting display panel for simplifying a manufacturing process and enhancing display quality. The organic light emitting display panel can include a first electrode disposed in each of subpixel areas of a substrate, bank layers disposed on the substrate at a boundary portion between adjacent subpixel areas, a lateral surface of the bank layers being hydrophilic, a first organic material layer disposed on the bank layers and the first electrode, a surface of the first organic material layer on the bank layers being hydrophobic, a second organic material layer disposed on the first organic material layer between adjacent bank layers, a third organic material layer disposed on the second organic material layer and the first organic material layer, and a second electrode disposed on the third organic material layer.
