Abstract
A front plane laminate useful in the manufacture of electro-optic displays comprises, in order, a light-transmissive electrically-conductive layer, a layer of an electro-optic medium in electrical contact with the electrically-conductive layer, an adhesive layer and a release sheet. This front plane laminate can be prepared as a continuous web, cut to size, the release sheet removed and the laminate laminated to a backplane to form a display. Methods for providing conductive vias through the electro-optic medium and for testing the front plane laminate are also described.
