PROBLEM TO BE SOLVED: To reduce power consumption by polarity inversion driving suitable for higher definition of display. SOLUTION: Carried out the polarity inversion driving wherein: a plurality of data lines are divided by (m) (m: a natural number of ≥2) to prescribe a plurality of blocks; data signals having the same polarity are outputted for the same block and data signals having the opposite polarities are outputted for mutually adjacent blocks; and the blocks are regarded as inversion units and the polarities of the data signals are inverted by specified periods.
