Abstract:
1. An organic light emitting device, comprising: 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 first electrode, the intermediate electrode and the second electrode, 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 the first electrode, the intermediate electrode and the second electrode 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, wherein 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, wherein each of the stacked organic light emitting elements comprises a first electrode, a first organic material layer, one intermediate electrode, a second organic material layer, a second electrode, and a connection electrode that connects the first electrode and the second electrode, a first group of electrodes of each of the stacked organic light emitting elements are the first electrode and the second electrode, which are connected by the connection electrode, and a second group of electrodes thereof are the one intermediate electrode, and as a form, in which the connection electrode, which forms the first group of electrodes of one stacked organic light emitting element among the stacked organic light emitting elements, is directly connected to the intermediate electrode which is the second group of electrodes of another stacked organic light emitting element, is provided, the first group of electrodes of the stacked organic light emitting elements are continuously connected in series and the second group of electrodes thereof are continuously connected in series, and each of the stacked organic light emitting elements is driven by the alternating current power source.
