Driving method of liquid crystal display device and liquid crystal display device

A method for driving a liquid crystal display device comprising a common electrode, a plurality of pixel electrodes, a liquid crystal material having spontaneous polarization sealed between the common electrode and the plurality of pixel electrodes, and switching elements provided for the plurality of pixel electrodes, respectively, for controlling voltage application to the liquid crystal material, comprising the steps of:

• writing image data by applying a voltage to the liquid crystal material corresponding to each of the plurality of pixel electrodes;
• and
• erasing the image data by applying a voltage to the liquid crystal material corresponding to each of the plurality of pixel electrodes,
• wherein, during the erasure of image data, voltage application to the liquid crystal material by batch selection of a part or all of the plurality of pixel electrodes is performed a plurality of times.
