Abstract
An organic light emitting device (and a method for producing the device) includes a multilayered structure with a substrate layer providing a first electrode layer, a second electrode layer and at least one light emitting organic material layer between the first and second electrode layers. The second electrode layer includes at least two separate layers. That is, a semi-transparent metal electrode layer and a light transparent lateral conductor layer is deposited onto the light emitting organic material layer by depositing the semi-transparent metal electrode layer onto the light emitting organic material layer, depositing subsequently at least one protection layer thereupon and depositing the light transparent lateral conductor layer onto the protection layer.
