Abstract
An electrophoretic display device includes a first substrate and a second substrate that face each other, an electrophoretic element disposed between the first substrate and the second substrate, the electrophoretic element including electrophoretic particles, a display unit that has a plurality of pixels including the electrophoretic element, a common electrode that is formed on an electrophoretic element side of the second substrate, and a first control line and a second control line that are formed in either the first substrate or the second substrate. Each of the plurality of pixels includes a pixel switching element, a memory circuit that is connected to the pixel switching element, a switching circuit that is connected to the memory circuit, and a first pixel electrode and a second pixel electrode that are connected to the switching circuit and are disposed to face the common electrode. The switching circuit includes a first switch that controls a conductive state between the first control line and the first pixel electrode in accordance with an output signal of the memory circuit and a second switch that controls a conductive state between the second control line and the sec…
