An organic light emitting display includes a substrate; an organic light emitting diode on one surface of the substrate; an encapsulation substrate located opposite and substantially parallel to the substrate with the organic light emitting diode therebetween; a filler layer on one surface of the encapsulation substrate facing the substrate; a first encapsulation layer located between the encapsulation substrate and the substrate and sealing the substrate and the encapsulation substrate together; and a second encapsulation layer located adjacent to the first encapsulation layer and between the encapsulation substrate and the substrate, wherein the filler layer and the second encapsulation layer include a moisture absorbent.
