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 and the lower substrates. The liquid crystal molecules are vertical to the upper substrate when no voltage is applied, and a plurality of strip-like lower substrate common electrodes are disposed on the lower substrate and arranged in parallel substantially. The upper substrate common electrode and the pixel electrode provide an electric field perpendicular to the upper substrate, 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 to form a second viewing angle mode when a voltage is applied.
