Organic light-emitting display device and method for manufacturing the same

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.
