Abstract
A method of fabricating a fringe field switching (FFS)-liquid crystal display (LCD) device may have the following advantage. An inferior connection between the drain electrode and the pixel electrode may be prevented by preventing formation of a copper compound on the drain electrode, by performing a back channel etching after patterning a pixel electrode, and by performing a wet strip rather than a dry strip. This may result in a direct contact between copper and ITO, thereby reducing the number of mask processes.
