Abstract: An LCD panel is provided, which includes a substrate, a polarizing sheet disposed on a surface of the substrate, and a device disposed on another surface of the substrate. The device forms a device area. The LCD panel further includes a shielding layer, which is embedded within the polarizing sheet or disposed on the upper surface or lower surface of the polarizing sheet. The device area is blocked by the shielding layer to prevent generation of a photo leakage current. The present invention has the following advantages. The shielding layer and a poly-silicon layer are individually formed, thereby avoiding a damage caused by static electricity between a poly-silicon layer and a shielding layer (that is caused by forming the poly-silicon layer onto the surface of the shielding layer in the prior art), as well as reducing the manufacture of the metal-shielding layer of traditional LTPS technology, thereby reducing production costs.
