<P>PROBLEM TO BE SOLVED: To provide a liquid crystal driving device that suppresses deterioration in image quality even if variations of bias potential or the like occur when a liquid crystal panel is driven by n lines inversion drive of a simultaneous selection driving method for simultaneously selecting a plurality of lines and the like. <P>SOLUTION: A liquid crystal driving device 100 for driving a liquid crystal panel 20 includes: a common driver 120 and a segment driver 134 for driving the liquid crystal panel 20 by an S lines simultaneous selection driving method, where S is a natural number not less than 2; and a polarity inversion controlling circuit 200 for performing polarity inversion control of driving signals of the liquid crystal panel 20 generated by the common driver 120 and the segment driver 134 for each n lines, where n is a natural number. At one or a plurality of timings in W frames, where W is a natural number, a polarity inversion period of each driving signal is increased or decreased by P horizontal scan periods, where P is a natural number. <P>COPYRIGHT: (C)2013,JPO&INPIT |
