ABSTRACT:
A liquid crystal display (LCD) device is disclosed which defines an open area of a lower substrate by a common electrode, for preventing stitching spots and changes of the aperture ratio by the bonding process on a large-sized LCD panel, which includes first and second substrates facing each other at a predetermined interval therebetween; gate and data lines crossing each other on the first substrate to define a pixel region; a common line in parallel to the gate line; a thin film transistor at a crossing portion of the gate and data lines; a plurality of common electrodes connected to the common line at fixed intervals in the same direction as the data line; a pixel electrode in contact with a drain electrode of the thin film transistor, between the common electrodes at fixed intervals; a black matrix layer provided on the second substrate, inside the outermost-opening limiting line of the first substrate (below the bonding margin); and a color filter layer provided on the second substrate.
