Organic light-emitting device

摘要

The present invention provides an organic light emitting device including: a substrate; and two or more stacked light emitting elements, which comprise a first electrode, at least one intermediate electrode, a second electrode, and an organic material layer disposed between the electrodes, the stacked organic light emitting elements including a first group of electrodes electrically connected to each other such that among the electrodes, at least two electrodes, which are not adjacent to each other, become a common electric potential, and a second group of electrodes which include one electrode among electrodes which are not electrically connected to the first group of electrodes, or at least two electrodes which are not electrically connected to the first group of electrodes and are electrically connected to each other so as to be a common electric potential without being adjacent to each other, in which the stacked organic light emitting elements are disposed at an interval apart from each other on the substrate and driven by an alternating current power source such that a form, in which a first group of electrodes of one stacked organic light emitting element among the stacked organic light emitting elements are directly connected to a second group of electrodes of another stacked organic light element, is continuously repeated.
