Provided are a display device which may be capable of eliminating display irregularities due to the difference in the charging rate between lines, while preventing increase in heat generation and power consumption by the device, and a circuit and method for driving the same. In a liquid crystal display device employing both a 2-line dot-inversion drive method and a charge-sharing method, a charge-sharing period (TB) within a horizontal scanning period (2H period) in which the polarity of each data signal is the same as that in one horizontal scanning period previous thereto, is set to be longer than a charge-sharing period (TA) within a horizontal scanning period (1H period) in which the polarity of each data signal is different from that in one horizontal scanning period previous thereto. Thus, a charge period within the 2H period can be shorter than that within the 1H period.
