Patent ID: 8049829

Claim:
A TFT substrate of a LCD panel, said TFT substrate comprising: a substrate; and a plurality of pixel units on said substrate, each pixel unit comprising: four lines on four sides of said pixel unit, comprising a first gate line, a second gate line, a first data line, and a second data line, said first gate line and said second gate line on two opposite sides of said pixel unit and parallel to each other, and said first data line and said second data line on other two opposite sides of said pixel unit and perpendicular to said first gate line and said second gate line; a pixel electrode layer in said pixel unit and said pixel electrode layer overlapping at least one of said four lines; a thin film transistor in said pixel unit; a first light-shielding layer in said pixel unit and near a first side of four sides of said pixel unit, the first light-shielding layer being disposed over a border of the line on the first side and extending toward a center of four lines, said first light-shielding layer being formed together with the first data line or the second data line and parallel to the first gate line or the second gate line; and a second light-shielding layer in said pixel unit and near a second side of said pixel unit, the second light-shielding layer being disposed over a border of the line on the second side and extending toward the center of four lines, said second light-shielding layer being formed together with the first gate line or the second gate line and parallel to the first data line or the second data line.
