Liquid crystal display device

A liquid crystal display device is composed of a liquid crystal display panel which includes liquid crystal pixels arranged in a matrix form and each having liquid crystal held between a pixel electrode and a common electrode, scanning lines arranged along the rows of pixels, signal lines arranged along the columns of pixels and pixel switching elements arranged near intersections between the scanning lines and the signal lines and each driven via a corresponding scanning line, and a display control circuit which controls the display panel. The display control circuit is configured to simultaneously drive all of the scanning lines, transition the potentials of the signal lines to a value substantially equal to potential of the common electrode in a state where the scanning lines are driven within a one-frame period, and turn off a power source after a preset period of time required for the transition has elapsed.
