Abstract

Disclosed is a liquid crystal display device () provided with a backlight part () that has a light-emitting diode (light source), and a liquid crystal panel (display part) () that includes a plurality of pixels (P) and displays information using illumination light from the backlight part (). A video generating device (control part) () decides, in a frame in which a gray-scale transition occurs, at least a length of either an OFF period of the light-emitting diode in a first half of the frame or an ON period of the light-emitting diode in a latter half of the frame, based on the time information from the time information generating part (), and outputs an instruction signal to a light source driving part () in accordance with the decided OFF or ON period for driving the light-emitting diode.
