Organic light emitting display device and mother substrate thereof

A mother substrate of an organic light emitting display device comprising:

• a plurality of organic light emitting display devices comprising data lines and scan lines disposed on a substrate;
• and
• scribing lines arranged horizontally and vertically between adjacent organic light emitting display devices, the scribing lines partitioning the substrate into rows and columns of regions, each region comprising an organic light emitting display device,
• wherein the data lines of an organic light emitting display device formed inside a region defined by first, second, third, and fourth scribing lines extend out of the region and are electrically coupled with a first pin-contact unit formed outside the first scribing line, and
• wherein the scan lines of the organic light emitting display device formed inside the region defined by the first, second, third, and fourth scribing lines extend out of the region and are electrically coupled with a second pin-contact unit formed outside the second or third scribing line, which are orthogonal to the first scribing line and parallel with each other.
