Abstract
This specification relates to an electrophoretic display device, and particularly, to an electrophoretic display device capable of reducing power consumption by blocking a leakage current generated from a Power On Reset (POR) circuit which resets each driver Integrated Circuit (IC) at an initial period, whereby a transistor as an active element connected to a POR circuit may be turned on by applying a positive voltage, other than a power supply voltage, to a gate thereof at an image update period to drive a bias block, and thereafter turned off at an image static period, thereby blocking a leakage current and accordingly reducing power consumption.
