Abstract:
1. A method for manufacturing an organic light-emitting display device, comprising: forming a thin film transistor having source/drain electrodes, on a substrate; forming a passivation layer on the source/drain electrodes; forming a via hole exposing one of the source/drain electrodes, in the passivation layer; forming a first pixel electrode on the passivation layer, the first pixel electrode being coupled to the exposed source/drain electrode and extending to a side wall of the via hole; forming a planarization layer on the first pixel electrode; forming a first planarization pattern filling the via hole in which the first pixel electrode is located and exposing a portion of the first pixel electrode on the passivation layer; forming a second planarization pattern at each end of the first pixel electrode; and forming a pixel defining layer on the first pixel electrode, the pixel defining layer having an opening exposing a portion of the first pixel electrode, wherein an upper surface of the second planarization pattern is coplanar with an upper surface of the first pixel electrode, and wherein the pixel defining layer overlaps a second planarization pattern, and the opening overlaps the via hole.
