Abstract
There is specified an illumination drive line assigned to a capacitive luminescent element which is connected to a single scanning line and is to be illuminated in accordance with an input video signal during a scanning period. A first potential lower than an illumination threshold voltage of the capacitive luminescent element is applied to a single scanning line, and a second potential higher than the illumination threshold voltage is applied to the scanning lines other than the single scanning line. A drive current is supplied to the illumination drive line for forwardly applying a positive voltage higher than the illumination threshold voltage to the capacitive luminescent element to be illuminated. A third potential slightly lower than the illumination threshold voltage is applied to the drive lines other than the illumination drive line. During a reset period defined between scanning periods, the second potential is applied to all the scanning lines, and a fourth potential equal to the second potential is supplied to the drive line other than the non-reset drive line.
