Abstract
An organic light emitting display including an ultraviolet protecting layer and a method of manufacturing the same include a lower substrate; an ultraviolet hardening adhesive formed on the lower substrate; a driving unit and a light emitting unit deposited on the lower substrate and surrounded by the ultraviolet hardening adhesive; an encapsulation layer covering the driving unit and light emitting unit and preventing moisture and oxygen penetration from an outside; an upper substrate arranged on the encapsulation layer facing the lower substrate and fixed by the ultraviolet hardening adhesive; and an ultraviolet ray blocking film formed in a region to block the driving unit and the light emitting unit from being irradiated by UV rays radiated to harden the ultraviolet hardening adhesive. The ultraviolet ray blocking film is disposed in the encapsulation layer or on the upper substrate to protect the driving unit and light emitting unit from ultraviolet rays.
