ABSTRACT:
The present invention relates to a liquid crystal display panel and a fabricating method thereof that is capable of enhancing crystallization efficiency of an active layer and simplifying the fabricating process. A fabricating method of a liquid crystal display panel includes forming a gate electrode on a substrate; forming a gate insulating film on the gate electrode formed thereon; forming an amorphous silicon film on the gate insulating film; forming an insulating pattern on the amorphous silicon film; crystallizing the amorphous silicon film into a polycrystalline silicon film using a derivative metal, the polycrystalline silicon film having source, drain and channel areas, wherein the insulating pattern overlaps the channel area of the polycrystalline silicon film; and forming source and drain electrodes on the polycrystalline silicon film, wherein the source and the drain electrodes contacting the source and drain areas of the polycrystalline silicon film, respectively.
