<P>PROBLEM TO BE SOLVED: To solve the problem, wherein the maximum value of potential difference driven with an output amplifier is the same, both when charge recovery is performed during column reverse drive and when it is not performed, and there is not much effect, when attention is focused on power consumption. Ž<P>SOLUTION: This data line driving circuit for the liquid crystal display device includes first data lines applied with a positive potential; second data lines applied with a negative potential, comparison units that compare a reference voltage with the potential of the first data lines or the second data lines; and switches that are controlled so that the first data lines and the second data lines are set to a connection state or to an interruption state, according to the comparison result by the comparison units.
