Patent ID: 7923736

Claim:
A flat panel display comprising: a light emitting element; and a thin film transistor, electrically connected to the light emitting element, wherein the thin film transistor comprises: a gate electrode disposed on a substrate, a gate insulating layer disposed on the gate electrode, a semiconductor layer disposed on the gate insulating layer and crossing over the gate electrode, wherein the semiconductor layer is crystallized by a metal induced lateral crystallization (MILC) technique, an inter-insulating layer disposed on the semiconductor layer and comprising source and drain contact holes that expose portions of the semiconductor layer, wherein at least one edge of each of the source and drain contact holes of the inter-insulating layer overlaps the gate electrode, source and drain electrodes disposed on the exposed portions of the semiconductor layer in the source and drain contact holes, respectively, and a pixel electrode contacting one of the source electrode and the drain electrode, wherein the semiconductor layer comprises metal induced crystallization (MIC) regions corresponding to the exposed portions of the semiconductor layer in the source and drain contact holes.
