Abstract
When a forward bias is applied between a selected unit electrode of scanning electrodes and a selected unit electrode of data electrodes to cause a selected pixel concerning both of the selected unit electrodes to emit light, and a reverse bias is applied between nonselected unit electrodes of the scanning electrodes and nonselected unit electrodes of the data electrodes, thereby preventing crosstalk caused by a semi-excited state of the nonselected pixels, all of the scanning electrodes and all of the data electrodes are short-circuited once, immediately before a predetermined unit electrode of the data electrode, which should be selected in accordance with selection of each of the unit electrodes of the scanning electrodes, is selected, to set all of the pixels at a zero bias.
