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.
A polarity inversion control device for a liquid crystal display panel having a plurality of pixels writeable with pixel voltages, comprising:
A driving method of a liquid crystal display device comprising a liquid crystal panel which includes a plurality of pixels, applies pixel voltages of different frame periods to the pixels, and inverts polarities of the pixel voltages according to a polarity inversion signal that is configured to employ either a first level or a second level for each of the frame periods when applying the pixel voltages to the pixels, the method comprising:
