Claim:
1. An electrophoretic display device comprising: an electrophoretic panel driven by a time division into an image update period and an image static period and having a plurality pixels defined thereon to display the image; a gate driver having at least one gate driver integrated circuit (IC) to apply a gate driving voltage to the plurality of pixels; a data driver having at least one data driver integrated circuit to apply a data voltage to the plurality of pixels; and a power supply unit to generate a gate high voltage, a gate low voltage, a positive voltage, a negative voltage and a ground voltage, wherein at least one of the gate driver integrated circuit and the data driver integrated circuit comprises: wherein the output of the positive voltage from the power supply unit to the data driver or the gate driver is stopped at a time point when the image static period starts such that the positive voltage is not supplied to the gate of the thin film transistor.
