PROBLEM TO BE SOLVED: To provide a liquid crystal driving gear which is a liquid crystal driving gear having a liquid crystal driving voltage forming means for generating a plurality of liquid crystal driving voltages of different voltage values within the means and outputting the voltages in the state of a lowered impedance and which realizes the relations of the ideal liquid crystal driving voltages by canceling the cause for display trouble, the fluctuation of the liquid crystal driving voltages and more particularly the offset possessed by the liquid crystal driving voltage forming means. SOLUTION: For all of the plurality of the liquid crystal driving voltages V0 to V5, means 20 for making the impedance lower which make the liquid crystal driving voltages lower in the impedance are respectively separately disposed. The means for making the impedance lower are so formed that the polarities of the respective output offset voltages generated by the means for making the impedance lower corresponding to the plurality of the applied voltages to be applied to the liquid crystal pixels at the time of non-selection among the plurality of the liquid crystal driving voltages are made the same.
