Patent ID: 7440063

Claim:
A method of fabricating a fringe field switching mode liquid crystal display device comprising: forming a common electrode and a gate metal on a board in sequence; etching the common electrode and the gate metal at the same time through a first mask process; forming a gate insulating layer, an active layer and a source/drain metal on the board in sequence; forming a channel in a thin-film transistor (TFT) part, substantially removing a gate metal at an opened region of the pixel area part and substantially opening a gate pad part; forming a passivation layer substantially on the entire surface of the board, and forming a contact hole on a drain electrode of the TFT part, removing an active layer remaining at the center of the pixel area part and exposing a gate pad part and a data pad part by performing a third mask process; and forming a pixel electrode on a predetermined region contacting the drain electrode in the TFT part, a predetermined region having the opening in the pixel area part and opened regions of the gate pad part and the data pad part through a fourth mask process.
