Claim:
1. A liquid crystal display device including a plurality of liquid crystal display drivers, each of the plurality of liquid crystal display drivers comprising: a power reception section electrically connected to a battery side, and configured to receive supply of power; a detection section configured to detect a singular state where a voltage of the battery side has fallen to a value less than or equal to a predetermined voltage value; a shifting section configured to receive a detection output of the singular state from the detection section to thereby shift to singular control; and a driver connection section configured to electrically connect the plurality of drivers to each other, wherein, if the detection section in one of the liquid crystal display drivers has detected the singular state, the shifting section corresponding to the detection section executes the singular control, the driver connection section corresponding to the detection section notifies the other liquid crystal display driver that the singular state has been detected to thereby cause the singular control of the other liquid crystal display driver to be started, and as the voltage used by the shifting section to execute the singular control, a voltage of a capacitor of a booster circuit of the one liquid crystal display driver is utilized.
