  • Random dispersion-type reflection polarizer
    Patent number: 9952363
    Abstract: A reflection-type polarizer according to the present invention has an improved bright line visibility phenomenon and a wider viewing angle, compared with a conventional dispersion-type reflection polarizer, and can maximize luminance improvement while minimizing optical loss. In addition, in connection with implementing a reflection polarizer, a group dispersion body can be formed through simple control, making it possible to maximize productivity improvement through process simplification.
