Abstract
Disclosed is an LCD device which facilitates to improve transmittance for each colored light by a design capable of realizing an optimal cell gap for each of sub-pixels, and a method for manufacturing the same. The LCD device comprises first and second substrates confronting each other; a liquid crystal layer between the first and second substrates; and first, second, and third sub-pixels, wherein a cell gap of the first sub-pixel is larger than a cell gap of the third sub-pixel.

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.
