Claim:
1. A method for driving a display device including an electrode, a counter electrode, and a display element placed between the electrode and the second counter electrode, the method comprising the steps of: in a first period, initializing or setting the display element to a first desired gray level while a first potential is applied to the counter electrode; in a second period following the first period, maintaining application of the first potential to the counter electrode, applying the first potential to the electrode, and switching a potential of the electrode and a potential of the counter electrode from the first potential to a second potential while maintaining application of a substantially zero voltage to the display element during the second period, independently of data to be displayed by the display element; and in a third period following the second period, initializing or setting the display element to a second desired gray level while the second potential is applied to the counter electrode, wherein a timing of switching the potential of the electrode is substantially the same as a timing of switching the potential of the counter electrode, and wherein the first potential and the second potential each have a value equal to or greater than a ground potential.
