Organic light emitting display device

An organic light emitting display device comprising:

• a first pixel;
• a second pixel adjacent to the first pixel in a first direction;
• a third pixel adjacent to the first pixel in a second direction that intersects the first direction;
• each of the first pixel, the second pixel, and the third pixel comprising a first sub pixel, a second sub pixel, and a third sub pixel;
• a first emission layer included in the first sub pixel;
• a second emission layer included in the second sub pixel;
• a third emission layer included in the third sub pixel;
• and
• a bank layer provided between the first emission layer and the third emission layer to separate the first emission layer and the third emission layer from each other,
• wherein the first emission layer, the second emission layer, and the third emission layer provided in the first pixel, the second pixel, and the third pixel are separated from each other,
• wherein the third emission layer included in the third sub pixel of the first pixel and the third emission layer included in the third sub-pixel of the third pixel is a common third emission layer that extends from the first pixel to the third pixel,
• wherein a thickness of the third emission layer is non-uniform, and
• wherein thickest portions of the third emission layer are in contact with the bank layer.
