Organic light emitting display device and method of fabricating the same

An organic light emitting display device (OLED), comprising:

• a substrate;
• a thin film transistor disposed on the substrate and including a source electrode and a drain electrode;
• a first insulating layer disposed on the substrate and the source and drain electrodes;
• a second insulating layer disposed on the first insulating layer and including a trench formed by reducing the thickness of a portion of the second insulating layer;
• a via hole formed in the bottom of the trench, through the first and second insulating layers, exposing the source electrode or the drain electrode;
• a first electrode disposed in the trench and connected to one of the source electrode and the drain electrode, through the via hole;
• a pixel defining layer disposed on the first electrode and having an opening exposing a portion of the first electrode;
• an organic electroluminescent layer disposed in the opening;
• and
• a second electrode disposed on an entire surface of the substrate having the organic layer, wherein,
• the opening has a first side wall and an opposing second side wall,
• the thin film transistor is disposed at the first side wall of the opening, and
• the trench extends continuously from the thin film transistor to the second side wall of the opening.
