To achieve thinner liquid crystal display panels and to reduce the power consumption for turning on a backlight during an image display operation to a minimum amount, a controller controls display operations of a main display panel and a sub-display panel via a first driver and a second driver. Based on the controlling of the display operations, the controller performs lighting control of LEDs of a backlight corresponding to the dimensions and position of the display panel used for image display. Accordingly, the backlight can be turned on for the display panel used for image display by consuming a minimum amount of power. Furthermore, the backlight includes a light-guiding plate and multiple LEDs and can emit light from both sides of the backlight, thus achieving reduction in thickness.
