  • Patent number: 8982437
    Abstract: A hologram recording film manufacturing method includes the steps of obtaining a laminated structure by alternately laminating M (where M?2) photosensitive material precursor layers including a photosensitive material and at least one (M?1) resin layer on one another, obtaining M photosensitive material layers, where at least two interference fringes with a desired pitch and a desired slant angle are formed on each of the M photosensitive material layers, from the M photosensitive material precursor layers by irradiating the laminated structure with a reference laser light beam and an object laser light beam, and making the slant angles of the M photosensitive material layers different from each other while retaining the pitch value, which is defined on a face of the photosensitive material layer, by irradiating the laminated structure with an energy ray from the laminated structure's one face side, and heating the laminated structure.

  • Patent number: 7312914
    Abstract: Between each transparent pixel electrode driven by TFT as a drive device and a common electrode, a polymer layer located in contact with the transparent pixel electrode and electrically active to change in color by electrochemical oxidization or reduction and a polymeric solid electrolytic layer located in contact with the polymer layer and containing a coloring agent are interposed. Since electrochemical oxidization or reduction brings about a color change, the contrast and the black concentration can be enhanced, and bronzing after long-time use does not occur.
