1. An electro-optic display comprising:
- a backplane;
a layer of electro-optic material disposed adjacent the backplane;
a protective layer disposed on the opposed side of the layer of electro-optic material from the backplane; and
a sealing layer of a metal or a ceramic contacting the backplane and the protective layer and extending therebetween, thus sealing the layer of electro-optic material from the outside environment.

14. A process for sealing an electro-optic display, the process comprising:
-
providing an electro-optic display comprising a backplane;
a layer of electro-optic material disposed adjacent the backplane; and
a protective layer disposed on the opposed side of the layer of electro-optic material from the backplane; and
vapor depositing a metal or a ceramic to form a sealing layer contacting the backplane and the protective layer and extending across the gap, thus sealing the layer of electro-optic material from the outside environment. - View Dependent Claims (15, 16, 17)

18. A process for depositing an electro-optic material on a substrate, the process comprising:
-
placing the substrate and a disposable member on a substantially flat support surface, with the disposable member lying adjacent the substrate, the disposable member having a thickness perpendicular to the support surface substantially the same as that of the substrate; and
moving a coating means relative to the support surface such that the coating means passes over the disposable member and thereafter over the substrate, the coating means depositing the electro-optic medium material on the substrate and at least a portion of the disposable member adjacent the substrate. - View Dependent Claims (19)

20. A sub-assembly for use in forming an electro-optic display, the sub-assembly comprising:
-
a layer of electro-optic material having first and second surfaces on opposed sides thereof;
a release sheet covering the first surface of the layer of electro-optic material, the release sheet being permeable to water vapor; and
a cover member covering the second surface of the layer of electro-optic material.
