Patent ID: 7488612

Claim:
A method for fabricating an liquid crystal display (LCD) device, comprising: disposing a silicon layer on a substrate; disposing a conductive metal layer on the silicon layer; patterning the conductive metal layer and the silicon layer to form an active pattern and a data line; the active pattern includes a source region, a drain region and a channel region; disposing a first insulation film on a portion of the substrate; removing the first insulation film and the conductive metal layer disposed in a portion of the active pattern; disposing a second insulation film on the substrate; forming a gate electrode on a portion of the active pattern where the second insulation film has been disposed; disposing a third insulation film on a portion of the substrate; forming a plurality of first contact holes defined through the second and third insulation films to expose a portion of the source and drain regions; forming a second contact hole defined through the first, second, and third insulation films to expose a portion of the data line; forming a source electrode connected to the source region within one of the plurality of the first contact holes and a data line within the second contact hole; and forming a pixel electrode and a drain electrode connected to the drain region within the other one of the plurality of first contact holes.
