Liquid crystal display device and method of the same

Method for fabricating liquid crystal display device of the present invention comprises the following steps: firstly, providing a substrate having a gate pattern on it, forming a first insulating layer, a semiconductor layer and a metal layer on the substrate and the gate pattern, etching the semiconductor layer and the metal layer to form a second pattern, forming a second insulating layer on the second pattern and the first insulating layer, etching the second insulating layer to form a third pattern on the second pattern and the first insulating layer and a channel area on the second pattern, forming a conductive layer on the gate pattern, the second pattern and the third pattern, etching the conductive layer to form a fourth pattern on the gate pattern, the second pattern and the third pattern, removing the metal layer of the second pattern under the channel, etching the part semiconductor layer of the second pattern under the channel, and forming a third insulating layer on the channel area and the third pattern.
