Patent ID: 7914354

Claim:
A method of fabricating an organic light emitting display, comprising: forming a thin-film transistor on a substrate to form a first structure, the thin-film transistor comprising a gate electrode, a source electrode and a drain electrode; forming an insulating layer on the first structure to form a second structure, the insulating layer having a via-contact hole that exposes one of the source electrode and the drain electrode; forming a reflective layer on the second structure, the reflective layer being connected to one of the source electrode and the drain electrode through the via-contact hole; forming a reflective layer pattern protruding in a horizontal direction by etching the reflective layer and removing the insulating layer disposed under an edge of the reflective layer pattern to form an undercut under the edge of the reflective layer pattern; forming a first electrode by forming a thin layer for a first electrode on the resultant structure, the first electrode being patterned by the undercut formed under the edge of the reflective layer pattern; forming an organic layer having at least an emission layer on the first electrode; and forming a second electrode on the organic layer.
