  • Polarizer and image display device
    Patent number: 11921369
    Abstract: An object of the present invention is to provide a polarizer having a high degree of alignment and an image display device including the polarizer. A polarizer of the present invention is a polarizer formed of a polarizer-forming composition containing a liquid crystal compound, a first dichroic material, and a second dichroic material, in which the polarizer has an array structure formed of the first dichroic material and the second dichroic material.
    Type: Grant
    Filed: September 22, 2020
    Date of Patent: March 5, 2024
    Assignee: FUJIFILM Corporation
    Inventors: Wataru Hoshino, Yoshiaki Takada, Yuzo Fujiki, Kengo Saito, Yasuhiro Ishiwata, Takashi Katou, Keisuke Ushirogata
