Title: LIQUID CRYSTAL DISPLAY PANEL
Abstract:
A liquid crystal display panel comprises: a substrate (20), a polarizing sheet (21) disposed on one surface of the substrate (20), and a device disposed on another surface of the substrate (20) and forming a device area. The liquid crystal display panel further comprises a shield layer (26) disposed in the polarizing sheet (21), on an upper surface of the polarizing sheet (21), or below a lower surface of the polarizing sheet (21). The shield layer (26) shields the device area to prevent the generation of a photo leakage current. The embodiment forms the shield layer (26) on the polarizing sheet (21), and prevents forming a polysilicon layer (25) on the shield layer (26) that has a certain thickness and a conical shape having an inclination angle. The embodiment forms the shield layer (26) and the polysilicon layer (25) separately, can prevent electrostatic discharge between the polysilicon layer and the shield layer (26) resulting from forming the polysilicon layer (25) on the surface of the shield layer (26) as in the prior art, and eliminate a process of fabricating a metal shield layer in the conventional LTPS fabrication process, thereby saving a process, and reducing manufacturing costs.
