Abstract
The driving method for a matrix type organic EL element comprises the steps of selectively applying an identical scanning voltage amplitude pattern to the plurality of row direction electrodes of two or more rows in accordance with the scanning voltage amplitude pattern applied to the row direction electrodes to simultaneously scan the electrodes, separately applying a signal voltage pattern, which is applied to the column direction electrodes, to the electrodes simultaneously scanned in the row direction through two sets or more of the plurality of column direction electrodes which are independent of each other, and simultaneously scanning two or more of a plurality of scanning lines to thereby form image information to be displayed in one frame.
