ABSTRACT:
A method for driving a display apparatus having display memory property is provided. In the method, the display apparatus includes an electrode group composed of at least a first electrode and a second electrode. The method includes the steps of: applying a voltage for performing writing of an display image between the first electrode and the second electrode; and attenuating an absolute value of a potential difference between the first electrode and the second electrode in a term within a holding period of the display image. Thereby, the deterioration of a holding characteristic owing to the influence of a residual DC can be prevented.
