The organic EL emission device includes an organic light emission layer for EL emission sandwiched between first and second electrode layers, at least one of which is transparent. At least the first electrode layer includes a plurality of electrodes arranged with spatial periodicity. The plurality of electrodes included in the first electrode layer together with adjacent regions in the second electrode layer including one or more electrodes form a plurality of electrode pair regions arranged with spatial periodicity. The method of driving the organic EL emission device is characterized in that electric fields having either different strengths or directions are applied with variation in a time-dependent manner to electrode pair regions adjacent to each other among the plurality of electrode pair regions. |
