ABSTRACT:
Electric charges accumulated in organic EL elements are discharged by applying a voltage for reverse-biasing the organic EL elements from at least one of a plurality of current drive circuits, which is connected to a line scanned at least one line ahead of a line to be scanned currently, to the line associated therewith and by connecting cathode connection lines connected to the current drive circuits other than the current drive circuit to be scanned currently and the line scanned at least one line ahead of the current drive circuit to be scanned currently to a predetermined biasing line. Thus, one or several lines accumulate charges corresponding to the reverse-biasing, so that the total power consumption can be reduced.
