Patent ID: 8773343

Claim:
A liquid crystal device comprising: signal lines; scanning lines; capacitive electric potential lines; pixels corresponding to each intersection of the signal lines and the scanning lines, each of the pixels including a selection switch, a pixel electrode, and a retentive capacitor interposed between the pixel electrode and one of the capacitive electric potential lines; a signal line driving circuit that supplies one of a first electric potential and a second electric potential to the signal lines in a write period included in each of subfield periods of a unit period, the unit period including even-numbered subfield periods having at least different lengths; a scanning line driving circuit that sequentially selects the scanning lines and supplies a scanning signal for turning on the selection switch in each write period; and a capacitive electric potential line driving circuit that supplies one of a low-level electric potential 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 the write period for the row corresponding to the corresponding capacitive electric potential line is terminated in each subfield period included in the 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; wherein the liquid crystal device is configured such that the polarity of the capacitive electric potential of the final subfield period is reversed twice during said final subfield period so that the polarity of the capacitive electric potential of the write period in said final subfield period is the same as the polarity of the capacitive electric potential of the write period of a subfield period consecutive to said final subfield period.
