1. An edge-sealed, encapsulated environmentally sensitive device comprising:
- at least one initial barrier stack comprising at least one decoupling layer and at least one barrier layer, wherein a first decoupling layer of a first initial barrier stack has an area and wherein a first barrier layer of the first initial barrier stack has an area, the area of the first barrier layer of the first initial barrier stack being greater than the area of the first decoupling layer of the first initial barrier stack, and wherein the first barrier layer of the first initial barrier stack is in contact with a third barrier layer or an optional substrate, sealing the first decoupling layer of the first initial barrier stack between the first barrier layer of the first initial barrier stack and the third barrier layer or the optional substrate;
an environmentally sensitive device adjacent to the at least one initial barrier stack; and
at least one additional barrier stack adjacent to the environmentally sensitive device on a side opposite the at least one initial barrier stack, the at least one additional barrier stack comprising at least one decoupling layer and at least one barrier layer, wherein a first decoupling layer of a first additional barrier stack has an area and wherein a first barrier layer of the first additional barrier stack has an area, the area of the first barrier layer of the first additional barrier stack being greater than the area of the first decoupling layer of the first additional barrier stack, wherein the first barrier layer of the first additional barrier stack is in contact with a fourth barrier layer, sealing the first decoupling layer of the first additional barrier stack between the first barrier layer of the first additional barrier stack and the fourth barrier layer, and wherein at least one barrier layer of at least one initial barrier stack is in contact with at least one barrier layer of at least one additional barrier stack, sealing the environmentally sensitive device between the at least one initial barrier stack and the at least one additional barrier stack forming an environmentally sensitive device seal, wherein an oxygen transmission rate through the environmentally sensitive device seal is less than 0.005 cc/m2/day at 23°
C. and 0% relative humidity.

Abstract
An edge-sealed, encapsulated environmentally sensitive device. The device includes at least one initial barrier stack, an environmentally sensitive device, and at least one additional barrier stack. The barrier stacks include at least one decoupling layer and at least one barrier layer. The environmentally sensitive device is sealed between the at least one initial barrier stack and the at least one additional barrier stack. A method of making the edge-sealed, encapsulated environmentally sensitive device is also disclosed.
