Abstract: Disclosed is an organic light emitting display device that includes a foreign matter compensation layer on an inorganic layer. A passivation layer and a second inorganic layer are in direct contact with each other at the edge of the substrate. Accordingly, the number of interfaces between the inorganic layers is decreased. Thus, even if the organic light emitting display device is bent, a moisture permeation path, which may be unexpectedly formed, can be minimized.

Abstract: The present disclosure provides an organic light emitting display that may comprise: 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 formed on a substrate having a Thin Film Transistor (TFT) formed on the substrate; and an upper encapsulation layer, which is formed of an aluminum oxide-based material, is formed in a single layer, and is disposed on the substrate on which the organic light emitting device (OLED) is formed, wherein a Water Vapor Transmission Rate (WVTR) of the upper encapsulation layer is smaller than or equal to 10−2 g/m2/day.
