Abstract
An active matrix organic light-emitting diode comprising an organic light-emitting diode portion. The organic light-emitting diode portion comprising: an underlayer having a top surface and bottom surface; a first electrode layer which is deposited and patterned on the top surface of the underlayer such that at least a portion of the underlayer is exposed, wherein the deposited first electrode layer comprises a top surface, a bottom surface and sidewalls disposed between the top and bottom surfaces, the sidewalls are positioned adjacent to the exposed portion of the underlayer; a passivation layer deposited on the exposed portion of the underlayer and the peripheral regions of the first electrode layer such that the passivation layer covers the sidewalls and the peripheral regions of the first electrode layer; a transparent conductor layer deposited on the passivation layer and the non-peripheral regions of the first electrode layer; and a second electrode layer deposited on the transparent conductor layer.
