Abstract
An electrophoretic display device includes a substrate, an electrophoretic display film, a plurality of second electrodes, and a plurality of third electrodes. The electrophoretic display film is disposed on the substrate and includes a display medium layer and a first electrode. The second electrodes and the third electrodes are disposed on the substrate and located between the display medium layer and the substrate. A first voltage received by each of the second electrodes is controlled by a corresponding thin-film transistor. The third electrodes and the second electrodes are alternately disposed in a direction. The first voltage is different from a second voltage received by the third electrodes.
