Electrophoretic display device driving circuit, electrophoretic display device, and electronic apparatus

An electrophoretic display device comprising:

• a display unit that includes a plurality of pixels, each of the plurality of pixels including:
• an electrophoretic element, containing electrophoretic particles, that is provided between a pixel electrode and a common electrode that face each other;
• a pixel switching element;
• a memory circuit to which an image signal may be written through the pixel switching element;
• and
• a switch circuit that controls switching of the pixel electrode in accordance with an output based on the image signal in the memory circuit;
• a low-speed clock supply unit that supplies a low-speed clock;
• a high-speed clock supply unit that supplies a high-speed clock having a frequency higher than that of the low-speed clock;
• and
• a control unit, the control unit controlling writing of the image signal to the memory circuit on the basis of the high-speed clock when changing images, and controlling supply of a predetermined pixel potential to the pixel electrode through the switching control on the basis of the low-speed clock during a stand-by mode when images are not being changed.
