Patent ID: 8587760

Claim:
A method for manufacturing an LCD device including first, second, and third sub-pixels comprising: forming a first photoresist pattern on a first base, and forming a groove in the first base by etching a predetermined portion of the first base under the conditions that the first photoresist pattern is used as a mask; forming a conductive material layer on an entire surface of the first base; remaining the conductive material layer in the groove, and removing the photoresist pattern and the conductive material layer thereon; forming a gate insulating film on the entire surface of the first base including the conductive material layer, and forming a semiconductor layer, a source electrode, and a drain electrode on the gate insulating film; forming a passivation film on the entire surface of the first base including the source and drain electrodes, and forming a second photoresist pattern on the passivation film; removing predetermined portions of the passivation film, the gate insulating film, and the conductive material layer under the conditions that the second photoresist pattern is used as a mask; and forming a pixel electrode electrically connected with the drain electrode, and forming a common electrode arranged in parallel to the pixel electrode.
