  • Reflection plate, manufacturing method thereof, liquid crystal display device and manufacturing method thereof
    Patent number: 7042539
    Abstract: A reflection plate is formed so as to have a wavy surface, and to have uneven distribution of normal line directions of the surface in terms of a specific azimuth angle. The wavy surface is formed due to line-shaped protruding patterns and an insulation film layer. The protruding patterns intersect with one another to form concave portions each having a shape of a closed figure. The protruding patterns are formed by patterning such that they have almost uniform thickness.
    Type: Grant
    Filed: August 18, 2004
    Date of Patent: May 9, 2006
    Assignee: NEC LCD Technologies, Ltd.
    Inventors: Michiaki Sakamoto, Yuichi Yamaguchi, Hidenori Ikeno, Takahiko Watanabe, Hironori Kikkawa, Fumihiko Matuno
