Claim Text:
1. A method of manufacturing an organic light-emitting display device, the method comprising: forming a pixel electrode; forming a hydrophobic material layer on the pixel electrode, wherein the hydrophobic material layer includes a hydrophobic material; forming a pixel-defining layer by patterning the hydrophobic material layer to expose a center portion of the pixel electrode and overlap outer portions of the pixel electrode; and selectively removing a residue of the hydrophobic material on an overlapping portion of the pixel-defining layer and the pixel electrode and the exposed center portion of the pixel electrode by surface treatment while preserving the hydrophobic material on an upper surface of the pixel-defining layer using the photo-resist layer to prevent an ink residue from forming on the upper surface of the pixel-defining layer in a subsequent formation of an intermediate layer.
