Abstract:
A liquid crystal device includes a capacitive electric potential line driving circuit that supplies one of a low-level and a high-level electric potential as a capacitive electric potential to each of the capacitive electric potential lines, reverses polarity of the capacitive electric potential as a write period for the row corresponding to the corresponding capacitive electric potential line is terminated in each subfield period included in a unit period, and, in a final subfield period included in the unit period, reverses polarity of the capacitive electric potential again at the time period of after reversing the polarity of the capacitive electric potential until terminating the corresponding final subfield period.
