A display device supplies, during a vertical blanking interval, a data signal for a gray display to each data signal line so as to cause the each data signal line to retain the data signal for the gray display. In at least one example embodiment, the data signal for the gray display has a polarity identical to a polarity of a data signal supplied immediately before the vertical blanking interval. This achieves a display device and a method for driving a display device in each of which, while an AC driving is carried out so that (i) data signals having opposite polarities are written to respective picture elements adjacent to each other within the same row, (ii) a polarity of a data signal supplied to each data signal line is reversed at least once during one vertical period, and (iii) a polarity of a data signal written to each picture element is reversed for every predetermined period, an effective value of a voltage applied to liquid crystal is less likely to differ between a picture element to which a data signal having a positive polarity is written and a picture element to which a data signal having a negative polarity is written. |
