Abstract
A method for making an electro-optic device or electro-optic display system having enhanced performance over conventional flat-panel displays, wherein a planarizing polymeric resin layer is spin-cast on a flat-panel backplane containing pixel circuitry. The spin-cast layer is cured to provide a flat backplane. Vias are opened in the cured polymeric resin to each pixel. Metal is deposited to fill the vias and to form a confluent, overlying metal layer on the upper surface. The metal layer is patterned and etched to form individual mirrors over each pixel. The metal acts as both a switchable electrode and as a high aperture, highly reflective mirror over each pixel. Electro-optic devices which may be made using such a process are also disclosed.
