Abstract
An LCD device and a method for manufacturing the same are disclosed in which if an overcoating layer is not formed on a color filter substrate, a gap between exposed pigments is filled with a column spacer material to increase a process margin. The LCD device includes first and second substrates facing each other, gate and data lines formed on the second substrate to cross each other, thereby defining pixel regions, a thin film transistor (TFT) formed in each portion where the gate lines cross the data lines, common and pixel electrodes alternately formed in the pixel regions, a black matrix layer formed on the first substrate to cover the gate lines, the data lines and the thin film transistor, color filter layers of a plurality of color films having a stripe shape and spaced apart from one another at a predetermined interval, wherein the color films partially overlap the black matrix layer, a filling pattern formed in regions between the respective color films, a column spacer formed on the black matrix layer and a predetermined portion of the color filter layers, and a liquid crystal layer formed between the first and second substrates.
