Abstract

A liquid crystal display device includes pixels having pixel electrodes and a common electrode. A liquid crystal material is held between the pixel electrodes and common electrode. Pixel switches are provided to supply video signals to the pixel electrodes. A plurality of memories are provided to store the video signals in a digital form supplied from the switches to the pixel electrodes. Connection controllers connect the memories to the pixel electrodes and periodically reverse polarities of the video signals output from the memories to the pixel electrodes with respect to potential of the common electrode. A potential setting terminal is provided and auxiliary capacitor lines connected to the potential setting terminal constitute capacitive coupling with the pixel electrodes. Separation circuits are provided to keep the auxiliary capacitor lines in an electrically floating state by electrically disconnecting the auxiliary capacitor lines from the potential setting terminal while the connection controllers connect the memories to the pixels.
