A pixel structure of a liquid crystal display panel includes a scan line, a data line, a thin film transistor (TFT), a pixel electrode, a light-shielding pattern, and a common line. The data line includes a first data line section and a second data line section composed respectively of the first material layer and second material layer and electrically connected to each other through a plurality of contact plugs. In addition, the pixel electrode is electrically connected to a drain of the TFT, and the light-shielding pattern, which is a floating metal, is disposed over the first data line section. The common line, the light-shielding pattern, and the second data line section are composed of the same material layer.
