13. A process for forming an electro-optic display, comprising:
-
providing a front plane laminate comprising a front substrate, a light-transmissive electrically-conductive layer, and a layer of electro-optic material; providing a backplane comprising at least one pixel electrode; and laminating the front plane laminate to the backplane, wherein an adhesive material is ink jet printed on to a peripheral portion of at least one of the front substrate and the backplane prior to the lamination, the adhesive material forming an edge seal sealing the electro-optic material from the outside environment after the lamination. - View Dependent Claims (14, 15, 16)

17. A process for forming an electro-optic display, comprising:
-
providing a backplane comprising at least one pixel electrode; ink jet printing an adhesive material on to a peripheral portion of the backplane; disposing on a central portion of the backplane lying within the adhesive material a front plane laminate comprising a front substrate, a light-transmissive electrically-conductive layer, and a layer of electro-optic material; and disposing at least one protective layer over the front plane laminate, the at least one protective layer extending beyond the periphery of the front plane laminate and contacting the adhesive material, thereby forming an edge seal around the front plane laminate. - View Dependent Claims (18, 19, 20)
