Abstract: An organic light emitting display device includes a substrate including an emission region and a non-emission region, an organic light emitting element which emits light, the organic light emitting element including a first electrode disposed on the substrate in the emission region, an organic light emitting layer disposed on the first electrode in the emission region, and a second electrode disposed on the organic light emitting layer, and a via insulation layer disposed on the substrate in the non-emission region thereof, the via insulation layer including an organic insulation material. The via insulation layer defines an opening therein in which the organic light emitting layer of the organic light emitting element is disposed.
