ABSTRACT:
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.
