Microscopic liquid crystal cells are fabricated in a collective process. Each of these micro-cells consists of pillars on which a cap is deposited. The caps provide a driving electrode and an alignment film for the liquid crystal. They are fabricated on a separate substrate and transferred onto the pillars by bonding and delamination from a release coating. The alignment film is made with a photoalignment material stabilized by a polymerized reactive mesogen. The latter also acts as a glue for bonding the cap to the pillars. The electrode is made up of a conducting polymer and is accessible through a via hole.
