Abstract
A liquid crystal display device includes a liquid crystal modulation element including a first electrode, a second electrode, and a liquid crystal layer, a potential difference providing unit that provides a potential difference between the first electrode and the second electrode, and an illumination optical system that illuminates the liquid crystal modulation element by using light from a light source. The liquid crystal display device includes a charge adjusting mode for reducing the intensity of an electric field generated by electric charge stored between the liquid crystal layer and at least one of the first electrode and the second electrode.
