ABSTRACT:
An organic electroluminescent display includes a substrate having an array portion with pixels, and a pad portion coupled to an external power supply. A semiconductor structure is formed on the substrate with a source electrode, a drain electrode and a pad. A passivation layer is formed on the semiconductor structure with via holes exposing regions of the source and the drain electrodes at the array portion and the pad at the pad portion. Portions of the passivation layer contacting the via holes between the array portion and the pad portion have the same thickness. A conductive layer fills the via holes. A pixel defining layer is formed over the entire surface of a flattening layer and the conductive layer with pixel regions exposing regions of the conductive layer at the array portion. An organic electroluminescent film is formed at each pixel region.
