Patent ID: 7868994

Claim:
A method for manufacturing a liquid crystal display device comprising: forming gate lines on a first substrate; depositing a gate insulating film, a semiconductor layer, and a source/drain metal layer over the first substrate, including the gate lines; forming data lines crossing the gate lines, source electrodes extending from the data lines, and drain electrodes separated from the source electrodes by a designated interval, and protrusions on the gate lines by selectively removing the source/drain metal layer and the semiconductor layer; forming a passivation film over the first substrate, including the data lines; forming contact holes exposing designated portions of the upper parts of the drain electrodes; forming pixel electrodes by depositing a transparent electrode on the surface of the passivation film, including the contact holes, and simultaneously forming compensation patterns about the protrusions, the compensation patterns having a height lower than that of the protrusions; forming column spacers having portions corresponding to the protrusions and edges corresponding to the compensation patterns; and forming a liquid crystal layer between the first substrate and the second substrate.
