An E-paper display device including an E-paper display panel and a display driver is provided. The E-paper display panel displays an image. The image includes a first frame and a second frame. The display driver is coupled to the E-paper display panel. The display driver drives the E-paper display panel to display the image. The display driver drives a first pixel group of the E-paper display panel in a first polarity and drives a second pixel group of the E-paper display panel in a second polarity to display the first frame during a first frame period. The first pixel group and the second pixel group are arranged in interlacing. The display driver drives the second pixel group of the E-paper display panel in the first polarity to display the second frame during a second frame period. Moreover, a method for driving an E-paper display panel is also provided.
