Abstract:
1. 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; one of the conductive layers which is not electrically connected with the conductive layers belonging to Group 1 to a common potential is a conductive layer belonging to Group 2, or two or more non-neighboring conductive layers of 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 by a sine wave alternating current voltage, a direct current voltage or a pulse voltage, wherein the voltage regulator is provided with a means of modulating the width or height of the sine wave or the pulse, and at least one intermediate conductive layer is formed of Ca.
