摘要： 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. The rest of the light transmitted through the changed pathway causes to, obtain the visual field angle of the liquid crystal display panel, while restrains the gray scale inversion of the images along with the part of the light passing through the liquid crystal display panel in the same direction as that of the light transmitted through a center of the liquid crystal display panel.
