PURPOSE: A method for driving a field emission display device is provided to reduce power consumption and prevent a damage of insulation of pixels by improving a driving method. CONSTITUTION: A scan pulse(SP) of positive polarity is supplied to a scan line of flat type field emission display device, sequentially. A data pulse(DP) synchronized with the scan pulse(SP) is applied to a data line. The scan pulse(SP) supplied to the scan line has the voltage level of positive polarity of 0 or more volt. A voltage level of the data pulse(DP) is determined according to the voltage difference between the data pulse(DP) and the scan pulse(SP). DC 5V is supplied to the scan line when the scan pulse(SP) is not supplied to the scan line. The scan pulse(SP) having the voltage level of 0 volt is supplied to the scan line when the scan pulse(SP) is supplied to the scan line. A ground voltage of 0 volt is supplied to the data line when the data pulse(DP) are not supplied to the data line. The data pulse having the voltage level of 10 V is supplied to the data line when the data pulse(DP) are supplied to the data line.
