Abstract

An electrophoretic display device is provided which is capable of preventing an afterimage and an image burn-in. Frames to make electrophoretic elements making up pictures of an active-matrix and a microcapsule-type electrophoretic display device be driven are divided into a plurality of white frames and black frames. The number of white frames to be used for writing on the electrophoretic elements by using a scanning driver and a data driver on one picture or between pictures is made to be equal to the number of black frames to be used for the writing and writing frames for particles having slow mobility responsive to variation in an electric field is provided last in the formation of the picture.
