Abstract:
1. A method for driving a display device comprising a gray scale storage display element wherein the gray scale storage display element comprises a pixel electrode and a common electrode, the method comprising the steps of: displaying gray by the gray scale storage display element; displaying black by the gray scale storage display element in a first period by application of a second potential to the pixel electrode and application of the second potential to the common electrode in a first sub-period of the first period and by application of a first potential to the pixel electrode and application of the second potential to the common electrode in a second sub-period of the first period; displaying white by the gray scale storage display element by application of the second potential to the pixel electrode and application of the first potential to the common electrode in a second period; displaying a predetermined gray scale by the gray scale storage display element by application of the first potential or the second potential to the pixel electrode and application of the second potential to the common electrode in a third period; and holding the predetermined gray scale by the gray scale storage display element by application of the first potential or the second potential to the common electrode and application of a potential equal to a potential applied to the common electrode to the pixel electrode in a fourth period.
