Abstract
When not receiving the next display-switch starting signal even after a specified time elapses from the application of a previous display driving voltage, a driving unit applies another preparatory driving voltage for generating a preparatory electric field capable of improving the response of colored particles to a driving electric field to an extent so as not to change the arrangement of the colored particles between pixel electrodes and a transparent electrode for a preparatory driving time.
