Patent ID: 8318521

Claim:
A method of manufacturing an organic light emitting display, the method comprising: forming an active layer having a source region, a drain region and a channel region on a substrate; forming a gate insulating layer on a substantially entire area of the substrate; forming a gate electrode and auxiliary wiring lines on the gate insulating layer; forming an interlayer insulating layer on the substantially entire area of the substrate; patterning the interlayer insulating layer to expose the source region, the drain region and the auxiliary wiring lines; forming a source electrode and a drain electrode coupled to the source region and the drain region, respectively; forming first auxiliary electrodes coupled to the auxiliary wiring lines; forming a planarization layer on the substantially entire area of the substrate; patterning the planarization layer to expose the source electrode or the drain electrode, and the first auxiliary electrodes; forming a first electrode coupled to the source electrode or the drain electrode; forming second auxiliary electrodes intersecting the first auxiliary electrodes; forming a pixel defining layer on the substantially entire area of the substrate; patterning the pixel defining layer to expose the first electrode and the first auxiliary electrodes; and forming an organic light emission layer and a second electrode on the substantially entire area of the substrate, wherein steps are formed at portions of the first auxiliary electrodes on steps of the auxiliary wiring lines and the interlayer insulating layer, and the second electrode is coupled to the first auxiliary electrodes through contact regions where the first auxiliary electrodes are exposed due to their steps.
