A lateral electric field type active-matrix addressing liquid crystal display device suppresses the lateral cross talk induced by the coupling capacitances (i.e., the parasitic capacitances) between the drain bus lines and the common bus line corresponding thereto with a simple structure. In each of the pixel electrodes, at least one electrically isolated light-shielding electrode is formed to extend along the drain bus lines that define the pixel electrode near the same drain bus lines. The light-shielding electrode is overlapped with a part of a corresponding one of the pixel electrodes to the pixel region in such a way that an insulating film intervenes between the light-shielding electrode and the part, the part extending along these drain bus lines in the vicinities thereof. The light-shielding electrode may be electrically connected to the corresponding one of the pixel electrodes at a point in the pixel region.
