  • Publication number: 20070171334
    Abstract: This invention provides a wide viewing angle liquid crystal display and a method for achieving wide viewing angle effect. The invention adds conductive nanoparticles in a liquid crystal layer of the present liquid crystal display. When a driving voltage is applied on the present liquid crystal display, an electric field applied on the liquid crystal layer is distorted by the conductive nanoparticles dispersed in the liquid crystal layer. A non-uniform electric field is hence formed in the liquid crystal layer and the liquid crystal molecules are prone to multi-directional alignments. As such, a wide viewing angle effect can be achieved.
