ABSTRACT:
An LCD device and a method for fabricating the same is disclosed, to decrease step coverage in color filter layers of LCD devices having different models formed on one mother substrate, which includes first and second substrates facing each other, in which a plurality of pixel regions are defined; a first black matrix layer on the second substrate except the pixel regions, so as to prevent light leakage; a second black matrix layer on the center of each pixel region of the second substrate, so as to decrease step coverage of color filter layer; the color filter layer in each pixel region; and a liquid crystal layer between the first and second substrates.
