Abstract
A liquid crystal display device with controllable viewing angle of the present invention has an upper substrate () on which an upper substrate common electrode () is disposed, a lower substrate () on which a pixel electrode is disposed, and a liquid crystal layer () sandwiched between the upper substrate () and the lower substrate (). The liquid crystal molecules are vertical to the upper substrate () in substance when no voltage is applied, and a plurality of parallel strip-like lower substrate common electrodes () are disposed on the lower substrate (). The upper substrate common electrode () and the pixel electrode () provide an electric field perpendicular to the upper substrate () in order to form a first viewing angle mode when a voltage is applied, the lower substrate common electrode () and the pixel electrode () provide an electric field perpendicular to the upper substrate () and an electric field parallel to the upper substrate () in order to form a second viewing angle mode when a voltage is applied. A method of driving the said liquid crystal display device is also disclosed.
