Patent ID: 8004176

Claim:
A method of fabricating an organic light emitting display, comprising: forming a thin film transistor over a substrate, the thin film transistor including a gate electrode, a source electrode, and a drain electrode; forming an insulating layer over the thin film transistor; forming a via hole in the insulating layer in a location corresponding to a portion of one of the source and drain electrodes; electrically connecting a pixel electrode to one of the source and drain electrodes through the via hole; forming a pixel defining layer over the pixel electrode in at least a location corresponding to the via hole, wherein the pixel defining layer comprises an opening in a location corresponding to a portion of the pixel electrode and is formed with a thickness of about 3000 Å or less; forming an emission layer over the pixel electrode; and patterning an opposite electrode, the opposite electrode being disposed over the emission layer; wherein the emission layer and the opposite electrode are formed to each the via hole.
