Patent ID: 7893438

Claim:
An organic light-emitting display (OLED) device, comprising: a substrate; a thin film transistor, having source/drain electrodes, located on the substrate; a passivation layer located on the source/drain electrodes and having a via hole exposing one of the source/drain electrodes; a first pixel electrode formed on the passivation layer, electrically coupled to the exposed source/drain electrode through the via hole; and a planarization pattern filling the via hole and exposing a portion of the first pixel electrode on the passivation layer; a pixel defining layer located on the first pixel electrode and having an opening that exposes the first pixel electrode; an organic layer located on the first pixel electrode exposed in the opening and having an organic emission layer; and an opposite electrode located on the organic layer, wherein an upper surface of the planarization pattern and an upper surface of the first pixel electrode are coplanar, wherein the upper surface of the planarization pattern is not coplanar with an upper surface of the pixel defining layer, and wherein the pixel defining layer overlaps a second planarization pattern situated at least one end of the first pixel electrode, an upper surface of the second planarization pattern being coplanar with the upper surface of the first pixel electrode.
