Abstract
To provide a liquid crystal display device and the like capable of achieving a function with which the charging polarity for the liquid crystal panel is not deviated even when the frame rate for writing to the liquid crystal panel changes dynamically only with simple structures and low power consumption. A polarity inversion control circuit is for supplying polarity inversion signals to the liquid crystal panel, and it is characterized to switch the levels of the polarity inversion signals in such a manner that a difference between an integrated value of frame periods when the polarity inversion signal is in a first level and an integrated value of the frame periods when the polarity inversion signal is in a second level becomes small.
