ABSTRACT:
A liquid crystal display panel is disclosed, in which each sub-pixel electrode has an opening in the center and a patterned conductive layer as a bias electrode is positioned relatively around the sub-pixel electrode. Upon being applied with a voltage, the liquid crystal molecules above the sub-pixel around the opening will tilt down outwardly and radially. Upon being applied with a bias voltage, the liquid crystal molecules above the bias electrode will be arranged parallel to the substrate due to the effect from the electric field. The liquid crystal layer may further comprise a chiral dopant, such that the molecules twist when they tilt.
