Abstract:
1. A method for fabricating an liquid crystal display (LCD) device, the method comprising: providing first and second substrates; depositing an amorphous silicon thin film and an n+ amorphous silicon thin film on the first substrate; forming an active layer on the first substrate by selectively etching the amorphous silicon thin film through a masking process; forming first and second ohmic contact layers on left and right sides of the active layer by selectively etching the n+ amorphous silicon thin film through the masking process; forming a first insulation film on the first substrate including the active layer and the first and second ohmic contact layers; forming a gate electrode to form a gap away from the first and second ohmic contact layers not to overlap with the first and second ohmic contact layers on the first insulation film; forming a second insulation film on the first substrate including the gate electrode; forming a pixel electrode on the second insulation film to overlap with a portion of the second ohmic contact layer; forming a third insulation film on the first substrate including the pixel electrode; forming a first contact hole exposing a portion of the first ohmic contact layer by removing a portion of the first to third insulation films; forming a second contact hole simultaneously exposing a portion of the second ohmic contact layer and the overlapped portion of the pixel electrode by removing a portion of the first to third insulation films; forming a source electrode electrically connected with the first ohmic contact layer through the first contact hole on the third insulation film; forming a drain electrode electrically connected with the second ohmic contact layer and the pixel electrode through the same second contact hole on the third insulation film; and attaching the first and second substrates.
