摘要： A liquid crystal display device is provided to prevent the influence by the depositioning of electric charge particles within the liquid crystal layer. An LCD(Liquid Crystal Display) device includes a liquid crystal modulation element(2R, 2B, 2G) including first and second electrode(103, 107), a liquid crystal layer(105) disposed between the first and second electrodes, a first alignment film(104) disposed between the first electrode and the liquid crystal layer, and a second alignment film(106) disposed between the second electrode and the liquid crystal layer. The LCD device includes a controller(3) that respectively provides first and second electric potentials to the first and second electrodes such that a sign of an electric field generated in the liquid crystal layer is cyclically inverted in a modulation operation state. The controller respectively provides third and fourth electric potentials to the first and second electrodes such that the sign of the electric field is fixed in a state other than the modulation operation state.
