Abstract:
1. A liquid crystal display (LCD) device comprising first and second substrates and a liquid crystal (LC) layer sandwiched between said first substrate and said second substrate, said first substrate mounting thereon: a plurality of gate lines and a plurality of common lines extending parallel to one another; a first insulation film covering said gate lines and said common lines; a plurality of drain lines extending normal to said gate lines and said common lines to define a plurality of pixels; a second insulation film covering said drain lines and said first insulation film; a common electrode and a pixel electrode extending parallel to one another in each of said pixels to apply said LC layer with an electric field parallel to said first substrate, said common electrode being made of a transparent material and having a protrusion protruding from both edges of said drain line, as viewed normal to said first substrate; and a light shield film extending along said common electrode in at least an area defined by two of said common lines, said light shield film having an overlapping portion overlapping at least a portion of said protrusion of said common electrode, as viewed normal to said first substrate, and electrically connected to said common electrode.
