Abstract
An electrophoretic display device includes a pair of substrates, a pixel, a first electrode being formed on one of the substrates for the pixel, a second electrode being formed on the other of the substrates, and an electrophoretic element which is held between the first electrode and the second electrode. The pixel includes a pixel switching element which is connected to a scan line and a data line, a memory circuit which is connected to the pixel switching element, and a switch circuit which is interposed between the memory circuit and the first electrode. The memory circuit is connected with a first power source line and a second power source line, and the switch circuit is connected with a first control line and a second control line. The first power source line and the second power source line cross each other at a first position of the pixel, and the first control line and the second control line cross each other at a second position of the pixel.
