Patent ID: 6979583

Claim:
A method of manufacturing an active electro-luminescent display, the method comprising the steps of: providing a substrate having a switching portion and a pixel portion; forming an active layer on the pixel portion; forming a gate insulating layer and a metal gate electrode on an approximate middle portion of the active layer; forming a source region and a drain region on exposed portions of the active layer by doping the exposed portions of the active layer heavily with impurities while using the metal gate electrode as a mask; disposing an insulating interlayer on the substrate and covering the active layer and the metal gate electrode; patterning the insulating interlayer so as to expose the source and drain regions; forming a source electrode and a drain electrode that is in contact with the exposed portions of the source and drain regions; forming a passivation layer on the insulating interlayer; forming a contact hole in the passivation layer for exposing the drain electrode; forming an anode electrode on the passivation layer, and covering the drain electrode so as to be in contact with the drain electrode; forming an organic electro-luminescent layer on the passivation layer and covering the entire anode electrode; and defining a cathode electrode on the organic electro-luminescent layer; wherein the anode electrode and cathode electrode being contacted with the organic electro-luminescent layer to supply electrons and holes into the organic electrode-luminescent layer.
