Claim Text:
1. An organic light emitting display comprising: an organic light emitting device (OLED) including a first electrode, an organic layer including a light-emitting layer, and a second electrode, which are sequentially on a substrate having a Thin Film Transistor (TFT) on the substrate, and having a light-emitting area that corresponds to the first electrode, the organic layer, and the second electrode; a bank disposed on the organic light emitting device on an area that is other than the light-emitting area, and having a bank hole that exposes the first electrode at the light-emitting area; and an upper encapsulation layer, which is formed of an aluminum oxide-based material, is formed in a single layer, is disposed on the substrate on which the organic light emitting device (OLED) is formed, and is directly contacting the second electrode of the OLED, wherein a water vapor transmission rate of the upper encapsulation layer is smaller than or equal to 10 wherein the upper encapsulation layer has a thickness of 20 to 50 nm, and wherein a density of the upper encapsulation layer ranges from 2.7 to 3.0 g/cm
