Abstract:
1. A liquid crystal display device comprising a liquid crystal material sealed in a gap formed by at least two substrates; and switching elements corresponding to respective pixels, for controlling selection/non-selection of voltage application to control light transmittance of the liquid crystal material, and having a first display function that displays an image by applying a voltage to the liquid crystal material through the switching elements, and a second display function that stops the application of voltage to the liquid crystal material through the switching elements and retains a display state just before the application of voltage is stopped, wherein an image display is performed by carrying out a switching between a first driving system in which a selection period of the switching elements just before the stop of the application of voltage for executing the second display function is longer than a selection period of the switching elements in the first display function and a second driving system in which the selection period of the switching elements just before the stop of the application of voltage for executing the second display function is equal to the selection period of the switching elements in the first display function.
