A display device includes: data-line pairs arranged side by side along a first direction; gate lines arranged side by side along a second direction; a display section including pixels each disposed at an intersection of a data-line pair and a gate line and connected to one or both of the data-line pair; a data-line drive circuit supplying a positive-phase data signal to one of the data-line pair and a negative-phase data signal to the other, and allowing the data-line pair to stay in a high-impedance state before writing of an image signal to the pixels; and a short circuit putting the data-line pair in a short-circuit state while the data-line pair stays in the high-impedance state, and then releasing the short-circuit state Following the release of the short-circuit state, the positive-phase data signal or/and the negative-phase data signal are written into the pixel as the mage signal.
