Liquid crystal display device

A liquid crystal display device comprising a liquid crystal panel and displaying images on the liquid crystal panel,

• wherein the liquid crystal panel includes:
• a plurality of scanning lines;
• a plurality of signal lines that intersect with the plurality of scanning lines;
• and
• thin film transistors provided at points of intersection of the plurality of scanning lines and the plurality of signal lines, respectively, and are connected to pixel electrodes,
• the liquid crystal display device further comprising:
• a booster circuit that generates a driving voltage from a power source voltage;
• a scanning line drive unit that selects the plurality of scanning lines in order and controls operations of the thin film transistors using the driving voltage generated by the booster circuit;
• and
• a timing control unit that controls the scanning line drive unit based on a display signal that includes a horizontal synchronization signal, a vertical synchronization signal, and an image signal,
• wherein the driving voltage includes:
• a selection voltage to be output to, among the plurality of scanning lines, one selected by the scanning line drive unit;
• and
• a non-selection voltage having a polarity opposite to that of the selection voltage,
• wherein, to the booster circuit, a reference synchronization signal is input, during a period while the scanning line drive unit selects none of the plurality of scanning lines,
• wherein the booster circuit, during the period, generates the non-selection voltage in synchronization with the reference synchronization signal, and
• wherein the scanning line drive unit, during the period, outputs the non-selection voltage generated by the booster circuit to the plurality of scanning lines.
