Abstract
A drive circuit is configured to, during a first period, sequentially select each of pairs of odd-number-th and even-number-th scanning lines and write an off electric potential into pixels corresponding the selected scanning lines; during a second period, sequentially select each of pairs of odd-number-th and even-number-th scanning lines and write gray-scale electric potentials in accordance with the selected odd-number-th scanning line into pixels corresponding to the selected odd-number-th and even-number-th scanning lines; and during a third period, sequentially select each of even-number-th scanning lines and write gray-scale electric potentials in accordance with the selected even-number-th scanning line into pixels corresponding to the selected scanning line. A common electric potential supply circuit reverses the polarity of a common electric potential during a polarity reverse period between the first period and the second period.
