ABSTRACT:
Pixel electrodes in a liquid crystal panel extend to cover the entire pixel regions. The light leakage is generated only on two sides of the pixel region due to the uncontinuous alignment of liquid crystal molecules when the liquid crystal panel is driven by dot inversion. Therefore, in the present invention, light-shielding layer is formed on only the corresponding region of the TFT substrate. The aperture ratio of the liquid crystal panel according to the present invention can increase and the light-shielding layer can be employed to repair the gate lines and data lines.
