Abstract
An electrophoretic display device includes a pair of substrates, an electrophoretic element that includes electrophoretic particles and that are held between the pair of substrates, and a display portion formed of a plurality of pixels. The display portion includes pixel electrodes, an opposite electrode, a first control line and a second control line. The opposite electrode is opposed to the plurality of pixel electrodes through the electrophoretic element. The first control line and the second control line are connected to each of the pixels. Each of the pixels includes a pixel switching element, a memory circuit, and a switch circuit. Switching of the switch circuit is performed by an output signal of the memory circuit to switch between a connected state where the pixel electrode is connected to the first control line and a connected state where the pixel electrode is connected to the second control line.
