1. A process for producing a color electro-optic display, the process comprising:

  • providing an electro-optic sub-assembly comprising an electro-optic layer and a light-transmissive electrically-conductive layer;

    laminating the electro-optic sub-assembly to a backplane comprising a plurality of electrodes such that the electro-optic layer is disposed between the backplane and the electrically-conductive layer;

    disposing a flowable material over the electrically-conductive layer; and

    disposing a color filter array over the electrically-conductive layer and aligning the color filter array with the electrodes of the backplane to form the color electro-optic display, wherein the material is a non-curable material which remains unchanged in the final display, and after alignment of the color filter array, dispensing a curable polymer around the periphery of the electro-optic layer and color filter array, and curing this polymer to form an edge seal which secures the electro-optic layer and color filter array to each other.
