PROBLEM TO BE SOLVED: To provide a method for driving a display device to be used for a display part or the like in electronic equipment, the method by which EMI noise signals are reduced. SOLUTION: The frequency of an inner clock signal InnerCLK to be inputted to a source driver IC is made different from the frequency of an input clock signal InputCLK inputted from a system apparatus in a blanking period, consequently the peak voltage level of a noise signal GNDnoise is reduced, wherein the noise signal GNDnoise is to be superposed on GND wiring of a data side PCB on which the source driver IC is packaged.
