Patent ID: 7250993

Claim:
A liquid crystal display device comprising: a first substrate; a second substrate; a first alignment film formed over said first substrate; a second alignment film formed over said second substrate; a liquid crystal layer interposed between said first alignment film and said second alignment film; a plurality of gate lines formed over said first substrate, a plurality of signal lines formed across said gate lines, and a pixel is constructed by surrounding a pair of said gate lines and a pair of said signal lines; a pixel electrode formed in said pixel, and the pair of said gate lines are formed upper side and lower side of said pixel electrode, and the pair of said signal lines are formed left side and right side of said pixel electrode; a left black matrix formed over said second substrate and overlapped a left edge portion of said pixel electrode with a first width; and a right black matrix formed over said second substrate and overlapped a right edge portion of said pixel electrode with a second width, wherein a rubbing treatment is applied to said first alignment film in a direction from upper left to lower right in said pixel, and wherein said second width is wider than said first width.
