Abstract
An encapsulated display device. The device includes a substrate, an environmentally sensitive display device adjacent to the substrate, and at least one first barrier stack adjacent to the environmentally sensitive display device. The barrier stack encapsulates the environmentally sensitive display device. It includes at least one first barrier layer and at least one first polymer layer. The encapsulated display device optionally includes at least one second barrier stack located between the substrate and the environmentally sensitive display device. The second barrier stack includes at least one second barrier layer and at least one second polymer layer. A method for making an encapsulated display device is also disclosed.
