Abstract:
1. A liquid crystal display device comprising: pixels including pixel electrodes and a common electrode; a liquid crystal material held between said pixel electrodes and said common electrode; pixel switches configured to provide video signals to said pixel electrodes; memories configured to store the video signals in a digital form supplied from said pixel switches to said pixel electrodes; connection control circuits configured to connect said memories to said pixel electrodes and to periodically reverse polarities of said video signals output from said memories to said pixel electrodes with respect to a potential of said common electrode; a potential setting terminal; auxiliary capacitor lines connected to said potential setting terminal and constituting capacitive coupling with said pixel electrodes; and separation circuits configured to keep said auxiliary capacitor lines in an electrically floating state by electrically disconnecting said auxiliary capacitor lines from said potential setting terminal while said connection control circuits connect said memories to said pixels.
