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

An organic light emitting display device comprising:

• a substrate;
• a sub-pixel comprising a pixel electrode, a counter electrode, and a light emitting layer between the pixel electrode and the counter electrode disposed on the substrate;
• a pixel defining layer surrounding the pixel electrode;
• a planarization layer covering the counter electrode and comprising an organic layer;
• an encapsulation layer covering the planarization layer;
• and
• an auxiliary electrode, comprising a vertical portion and a horizontal portion, in the planarization layer and directly contacting the encapsulation layer, the auxiliary electrode being electrically coupled to the counter electrode and being configured to apply a voltage to the counter electrode,
• wherein a first area defined by an interface between the auxiliary electrode and a first surface of the counter electrode overlaps a second area defined by an interface between a second surface of the counter electrode and the pixel defining layer, the first surface and the second surface of the counter electrode being opposing sides of the counter electrode, and
• wherein the horizontal portion of the auxiliary electrode overlaps with a portion of the pixel electrode along a direction perpendicular to the first area and the second area and does not extend entirely to a first edge and a second edge of the substrate, wherein the first edge and the second edge extend in a direction perpendicular to the first area and the second area.
