Abstract
A liquid crystal display has pixels in domains surrounded by data signal lines and scanning signal lines. Each of the pixels has a voltage holding device for a positive polarity and a voltage holding device for a negative polarity, two lines of voltage holding interconnections which always apply a maximum voltage and a minimum voltage of a voltage applied to the data signal lines formed for holding the voltage, and a switching device for switching between outputs from the voltage holding devices. One time or more within one frame time period thereof, the switching is performed between the voltage holding device for a positive polarity and the voltage holding device for a negative polarity.
