Organic light emitting devices and methods of fabricating the same

An organic light emitting device, comprising:

• a flexible substrate;
• a first electrode on the flexible substrate;
• and
• an organic light emitting layer on the first electrode,
• wherein the flexible substrate comprises:
• a polymer layer;
• a gas barrier layer on the polymer layer;
• polymer patterns on the gas barrier layer;
• and
• a metal line on a portion of the gas barrier layer, the portion of the gas barrier layer being exposed through the polymer patterns,
• wherein the polymer patterns have a lower surface in contact with the gas barrier layer and an upper surface in contact with the first electrode.
