An organic light-emitting display device and a method of manufacturing the same are disclosed. The organic light-emitting display device (OLED) may include a first substrate with an element region and an encapsulation region surrounding the element region, a second substrate facing the first substrate, an organic light-emitting element interposed between the first substrate and the second substrate and formed in the element region, and an encapsulant interposed between the first substrate and the second substrate and formed in the encapsulation region. The encapsulant may include both a first encapsulant and a second encapsulant. The second encapsulant formed within the first encapsulant and is adjacent to at least one of the first substrate and the second substrate.
