Abstract
The present invention provides a stacked organic light emitting device, comprising a first conductive layer, at least one intermediate conductive layer and a second conductive layer, and light emitting units disposed between the conductive layers, wherein at least two non-neighboring conductive layers among the conductive layers are conductive layers belonging to Group 1 such that they are electrically connected with each other to a common potential; at least one non-neighboring conductive layer among the conductive layers which are not electrically connected with the conductive layers belonging to Group 1 to a common potential are conductive layers belonging to Group 2 such that they are electrically connected with each other to a common potential; and the conductive layers belonging to Group 1 and the conductive layers belonging to Group 2 are connected with each other via a voltage regulator for alternately applying a positive voltage and a negative voltage.
