ABSTRACT:
An LCD device is disclosed in which column spacers for a cell gap are arranged between gate and common lines to reduce a contact area between the column spacers and an opposing substrate, and a stable cell gap is maintained over the whole panel by reducing variation of a thickness per area of a thin film transistor (TFT) substrate corresponding to the column spacers. The LCD device includes first and second substrates facing each other, gate and data lines formed on the first substrate to cross each other, and pixel regions, a thin film transistor formed in each portion where the gate and data lines cross, common and pixel electrodes alternately formed in the pixel regions, common lines formed adjacent to the gate lines substantially parallel to the gate lines, a first column spacer formed on the second substrate corresponding to a portion between the gate line and the common line, and a liquid crystal layer filled between the first and second substrates.
