Organic light emitting display device

An organic light emitting display device comprising:

• a substrate configured to include a sub-pixel defined into an emission region and a driving region;
• a first bank pattern disposed on the substrate and configured to define the emission region of the sub-pixel;
• a second bank pattern disposed on a part of an upper surface of the first bank pattern and configured to include an opening which exposes the emission region and a part of the driving region;
• and
• an organic emission layer disposed in the opening,
• wherein the opening is wider than the emission region.
