Abstract
A scanning line drive unit sequentially selects a plurality of scanning lines, and utilizes a drive voltage generated by the booster circuit to control the operation of a thin-film transistor. A timing control unit controls the scanning line drive unit on the basis of a display signal, which includes a horizontal synchronization signal, a vertical synchronization signal and an image signal. A reference synchronization signal is input to the booster circuit during a period in which the scanning line drive unit selects none of the plurality of scanning lines. A booster circuit generates a non-selection voltage in synchronization with the reference synchronization signal in the abovementioned period. The scanning line drive unit outputs the non-selection voltage generated by the booster circuit to the plurality of scanning lines in the abovementioned period.
