It is an object of the present invention to provide a liquid crystal display device with high color reproduction ability even when an area active backlight is driven. A liquid crystal display device (1) of the present invention drives a liquid crystal panel (2) and a backlight device (3), respectively, using a video signal input from outside. In the backlight device (3), a plurality of illuminating areas (Ha) are set on LED substrates (7) with respect to a plurality of display areas provided on the liquid crystal panel (2), and area active backlight drive is performed, which lights up light-emitting diodes (8) in the unit of the illuminating areas. When a backlight data processing part (lighting control part) (15) determines that a brightness signal value indicated for a blue light-emitting diode (light source of a predetermined color) (8b) is larger than brightness signal values indicated for other light-emitting diodes (8r, 8g), and determines that a value obtained by multiplying the brightness signal value indicated for the blue light-emitting diode (8b) by a predetermined ratio is equal to or more than the bright signal values indicated for the other light-emitting diodes (8r, 8g), the backlight data processing part (15) lights up the other light-emitting diodes (8r, 8g), using the brightness signal value indicated for the blue light-emitting diode (8b). |
