    Abstract: A day-night mirror (10) for a vehicle has a first sheet (12) of transparent material, a second sheet (14) adjacent and parallel to the first sheet has a first light reflective surface (16) facing the first sheet. The first and second sheets are joined along a predetermined peripheral region by a first wall (20), and a second wall of flexible material (22) extends between the first and second sheets along opposed edge regions. The sheets and walls together define a chamber (30) containing a predetermined volume of transparent fluid (32). A third sheet (36) having a light absorbing characteristic is positioned within the chamber to be moved by an actuator (40) between an active position, with the third sheet between the first and second sheets, and an inactive position, with the third sheet removed from between the first and second sheets.

    Abstract: @ This invention provides an optical filter comprises of a pair of solid polymer films, wherein (1) a first solid polymer film has a planar alignment of a cholesteric liquid crystal structure of either clockwise of counterclockwise helical structure, which alignment allows the light of a specified wavelength to be scattered selectively, and (2) a second solid polymer film has a planar alignment of a cholesteric liquid crystal structure of a helical structure whose helical direction is the opposite to that of the first solid polymer film, which alignment allows the light at the specified wavelength to be scattered selectively, wherein the optical axes of the first and second solid polymer films are made substantially parallel to each other. This invention also provides preparation methods of an optical filter mentioned above.
