Abstract
This invention relates to the field of electrophoretic displays. In particular, it relates to processes for the manufacture of multilayer color displays involving imagewise opening and filling display cells with display fluids of different colors. The color displays have improved contrast ratio, switching performance, reflectivity at the Dmin state and structural integrity.
