Patent ID: 8460982

Claim:
A method for manufacturing an array substrate of a fringe-field switching (FFS) type thin film transistor liquid crystal display (TFT-LCD) comprising: Step 1 : forming a first transparent conductive film and a first metal film on a transparent substrate sequentially, and then patterning the stack of the first transparent conductive film and the first metal film so as to form patterns including gate lines, gate electrodes, common electrodes and common electrode lines; Step 2 : forming a gate insulating film, a semiconductor film and an impurity-doped semiconductor film sequentially, and then patterning the stack of the gate insulating film, the semiconductor film and the impurity-doped semiconductor film so as to form patterns including gate connection holes in the PAD region and a semiconductor layer; and Step 3 : Ruining a second metal film, patterning the second metal film, then forming a second transparent conductive film and performing a lifting-off process so as to remove the second transparent conductive film on photoresist, and etching the exposed second metal film and the impurity-doped semiconductor film so as to form patterns including source electrodes, drain electrodes, TFT channels and pixel electrodes.
