  • Liquid crystal display device
    Patent number: 7327413
    Abstract: Disclosed are an apparatus for changing a pathway of light according to a visual field angle to relax a gray scale inversion and for use in a liquid crystal display device in a twisted nematic mode, and the liquid crystal display device having the same. The light pathway partially changing apparatus is disposed on a liquid crystal display panel changes the pathway of the light partially so that a part of the light is substantially transmitted in the same direction as the light proceeds while the rest of the light is transmitted through a changed pathway, in order to change a brightness of the light according to a visual field angle of a liquid crystal display panel to restrain a gray scale inversion of the images while the light passes through the liquid crystal display panel to make the images on the liquid crystal display panel.
