  • Patent number: 8233124
    Abstract: A liquid crystal display device is disclosed, which can control a viewing angle in vertical and horizontal directions without forming a specific liquid crystal display panel, the liquid crystal display device comprising a display screen including a plurality of color pixels and liquid crystal molecules; and a viewing-angle control pixel controlling the liquid crystal molecules, an alignment direction of the liquid crystal molecules being inclined to a vertical or horizontal direction in the display screen, wherein the viewing-angle control pixel is formed independently of RGB pixels, to thereby control the viewing angle in the horizontal and vertical directions.

  • Publication number: 20110183574
    Abstract: A liquid crystal display device and method of fabricating the device where the device can control a viewing angle in all directions without forming a white pixel. The liquid crystal display device includes a display control region that is controlled such that liquid crystal molecules are inclined and a viewing-angle control region that is controlled such that liquid crystal molecules are aligned in a horizontal or vertical direction, where a control voltage is supplied through a viewing angle control line independent of a common line for the display control region.
