An anti-aliasing filter includes a polymeric double-refraction plate
("DRP"). The DRP of the anti-aliasing filter has at least a first liquid
photo-polymerization ("LPP") layer disposed on the substrate, or on an
intervening layer(s) disposed on the substrate, and a first
liquid-crystal polymer ("LCP") layer is disposed on the first LPP layer,
the first DRP having a thickness selected so as to provide a selected
separation of oridinary and extraordinary light rays.
