Abstract
There is provided a method of making a curved barrier film, including: depositing a barrier layer between a first organic layer and a second organic layer to form a barrier film; and thermoforming or vacuum-forming the barrier film from a flat barrier film to a curved barrier film; wherein the barrier film includes the barrier layer having two opposing major surfaces, wherein the barrier layer includes buckling deformations and non-buckling regions; the first organic layer in direct contact with one of the opposing major surfaces of the barrier layer; and the second organic layer in direct contact with the other of the opposing major surfaces of the barrier layer.
