Abstract
A unit for driving an image display device capable of preventing occurrence of luminescent spots on a display plane due to a leakage voltage of the unit. The drive unit includes gate electrodes and cathode electrodes arranged so as to define a matrix by cooperation with each other. At least two reset pulses are applied to each of the gate electrodes during a period of time for which it is kept nonselected to cause a voltage increased due to the leakage voltage to be reduced to a level of a reference potential and the gate electrode is kept at an increased impedance during a period of time for which the gate electrode is kept from being fed with the reset pulses.
