Abstract
The present invention provides a liquid crystal display device capable of achieving a high response speed. The liquid crystal display device includes: an upper substrate and a lower substrate; and a liquid crystal layer disposed between the upper and lower substrates, the upper substrate including an electrode, the lower substrate including paired electrodes, the liquid crystal layer containing liquid crystal molecules that are aligned in parallel with the main surfaces of the upper and lower substrates with no voltage applied, the liquid crystal display device being configured to provide one of white display and black display by utilizing an electric field generated between the paired electrodes of the lower substrate to rotate the liquid crystal molecules in one direction in a plane parallel to the main surfaces, and the other of white display and black display by utilizing an electric field generated by the respective electrodes of the upper and lower substrates to rotate the liquid crystal molecules in the opposite direction from the one direction in the plane parallel to the main surfaces.
