ABSTRACT:
A liquid crystal display having a top plate and a bottom plate. The bottom plate includes a plurality of gate bus lines and a plurality of drain bus line arranged in a matrix on a substrate surface. A plurality of thin film transistors, each including a source, gate and drain, are formed at intersections of the gate and drain bus lines. A black matrix pattern, including a non-conductive black resin, is provided on the gate bus lines, the drain bus lines and the thin film transistors for shielding these elements from light generated by back lighting the display. A protective layer is formed on the black matrix pattern having contact holes for coupling the pixel electrodes to corresponding drain electrodes of the thin film transistors.
