Abstract
A liquid crystal display device includes a liquid crystal display panel having pixels, a light source which illuminates the display panel, and a control unit which controls the display panel and the light source. The control unit includes an insertion unit which causes the pixel to store a first voltage corresponding to a video signal in a first period within one frame period and to store a second voltage corresponding to a non-video signal in a second period that follows the first period, and a driving unit which enables the light source at least in a period corresponding to the first period in which the first voltage is held in the pixel, and disables the light source in a period corresponding to the second period in which the second voltage is held in the pixel, and is configured to set the first and second voltages at different independent values.
