ABSTRACT:
An active matrix electrophoretic display is driven. In a reset period Tr a reset voltage is applied to each pixel electrode. Next, in a writing period an applied voltage is applied to each of said pixel electrode during a time period corresponding to a gradation value designated by an image data. Next, a common voltage is applied to each of said pixel electrode, so that electric charge accumulated in each capacitor is taken away and no electric field is applied to each dispersal system, thereby a displayed image is held.
