Abstract
Provided are an organic light-emitting display device and a manufacturing method of the organic light emitting display device. The organic light-emitting display device includes: a substrate; a display unit formed on the substrate; an encapsulation substrate formed above the display unit; a first sealant bonding the substrate and the encapsulation substrate; a filler formed between the substrate and the encapsulation substrate; and a second sealant interposed between the first sealant and the filler so as to separate the filler from the first sealant, wherein a distance of a portion of the substrate and the encapsulation substrate is smaller than that of other portions of the substrate and the encapsulation substrate. Accordingly, penetration of impurities, such as oxygen or water, from the outside into the organic light emitting display device is prevented.
