Abstract
An organic light emitting device is provided. The device has a first electrode, an insulating strip disposed over the first electrode, and a bus line disposed on top of the insulating strip, such that the bus line is electrically insulated from the first electrode by the insulating strip. An integrated mask is disposed over the bus line, such that a portion of the bus line remains exposed vis-a-vis the insulating strip and the integrated mask. An organic layer is disposed over the first electrode, such that the organic layer is electrically connected to the first electrode. A second electrode is disposed over the organic layer, such that the second electrode is electrically connected to the organic layer, and such that the second electrode is electrically connected to the exposed portion of the bus line. A method of fabricating the device is also provided, which involves depositing the organic layer and the second electrode through the integrated mask, such that the second electrode is in electrical contact with the bus line.
