forming a first component comprising at least one first material on a first substrate;
forming a second component comprising at least one organic light emissive material and at least one adhesive material on a second substrate;
forming a third component, where the first component and the third component are larger in area than the second component; and
laminating the first component, the second component and the third component together such that
the third component is bonded to the first component in locations that are beyond the edges of the second component,
the second component is located between and encapsulated by the first component and the third component, and
the at least one first material and the at least one organic light emissive material form at least part of an organic electro-optic device located between the first substrate and the second substrate.
