Patent ID: 8279515

Claim:
An electrophoretic display device, comprising: a substrate; an electrophoretic display component layer, having a top surface and a bottom surface, the top surface having a first width and a first optical adhesive adhered thereon, the bottom surface being disposed on the substrate; a barrier layer, having a top barrier surface and a bottom barrier surface, the bottom barrier surface attached to the first optical adhesive, the top barrier surface attached to a second optical adhesive; a protective layer, having a second width and being attached to the second optical adhesive, wherein the second width is greater than the first width; and a sealant for sealing the sides of the electrophoretic display component layer, the barrier layer, and the protective layer onto the substrate, wherein the sealant cures upon exposure to light of predetermined wavelength; wherein at least one of the first optical adhesive and the second optical adhesive is capable of absorbing the light of predetermined wavelength and is adapted to expose the sealant.
