Claim Text:
1. A liquid crystal display panel comprising: first and second substrates, said first substrate having, a transparent insulating substrate; signal lines and scanning lines arranged on a display region on said transparent insulating substrate, the signal lines and the scanning lines crossing each other to form a matrix; a common line arranged in parallel with said scanning lines; an insulating film covering said signal lines, said scanning lines and said common line; and a lower electrode and an upper electrode arranged in a pixel part surrounded by said scanning lines and said signal lines to oppose to each other in an upper and lower positional relationship on said insulating film, said second substrate being arranged to oppose to said first substrate, wherein said common line is arranged to cross a center portion of said pixel part, said pixel part is divided by said common line into first and second regions, said upper electrode has a slit-shaped first opening in said first region and a slit-shaped second opening in said second region, said first opening is formed as being tilted, such that the slit forms a first angle with a reference line which is an extending direction of said common line, said second opening is formed as being tilted, such that the slit forms a second angle line-symmetrically to said first angle with reference to said reference line, said upper electrode and said lower electrode are arranged to be respectively overlaid on edge portions of said scanning lines and said signal lines, the edge portions existing along extending directions of said scanning lines and said signal lines, said second substrate includes a light shield film, said light shield film is formed in a region above a region where said scanning lines and said signal lines are formed in said pixel section, to extend along the region where said scanning lines and signal lines are formed, in a region where a first contact hole penetrating through at least said insulating film to reach a surface of said common line is formed and a region nearby, said light shield film is formed in a region corresponding to above at least a region extending outward from a top edge portion of the first contact hole, said light shield film does not extend over an entirety of said common line, and said light shield film covers ends of said slit-shaped first opening and said slit-shaped second opening on both sides of said pixel part.
