A method for viewing angle control of a hybrid-aligned liquid crystal (LC) cell is reported. The viewing angle of proposed structure can be controlled by using vertical switching, by which the tilt angle of LC is controlled, while the optical transmittance can be controlled by using horizontal switching, by which the optic axis (OA) of LC can be rotated. A 3-terminal electrode structure composed of the top common electrode, the bottom grid electrodes, and the bottom common electrode is employed for both the vertical switching and the horizontal one.
