Abstract: Provided are an encapsulating structure, an organic light-emitting display device including the encapsulating structure, and a method of manufacturing the same. The encapsulating structure includes a first barrier layer including a first inorganic layer having a first thickness; a plasma polymer layer on the first inorganic layer, the plasma polymer layer having a second thickness smaller than or equal to the first thickness; and a second barrier layer including at least one second inorganic layer on the plasma polymer layer. The at least one second inorganic layer has a third thickness, and the third thickness is smaller than or equal to the second thickness.

Abstract: A display apparatus includes a substrate, a display portion that includes a plurality of pixels disposed on the substrate, and an encapsulation portion that covers the display portion and includes a hybrid encapsulation layer that includes a plurality of inorganic layers and at least one organic layer that includes a plasma polymer. An end of the hybrid encapsulation layer includes a tip portion that includes an inorganic material and a multi-layered portion which extends from the tip portion toward a central portion of the substrate and in which the plurality of inorganic layers and the at least one organic layer are sequentially and alternately stacked, and a thickness of each of the inorganic layers and the organic layer decreases toward the tip portion.
