A liquid crystal display device includes a display-device substrate having a transparent electrode; an array substrate having a pixel electrode, a source line, a gate line, and a conductive line; a liquid crystal layer sandwiched between the display-device substrate and initially aligned vertically; and a controller that drives the liquid crystal layer by supplying an image signal to the source line and applying a liquid crystal driving voltage across the transparent electrode and the pixel electrode in synchronization with the image signal, the controller applying a voltage to the conductive line after the liquid crystal driving voltage is applied to the pixel electrode and while the liquid crystal driving voltage is not applied to the pixel electrode, thereby generating an electric field oriented in a direction intersecting the source line in a plan view between the conductive lines.
