Method for polishing a liquid crystal display

Abstract

A method for polishing a liquid crystal display panel is provided. The liquid crystal display panel is provided with a thin-film transistor substrate that is provided with a pad area thereon. The polishing method comprises the following steps. A protecting member is provided. The protecting member is bonded on the pad area of the thin-film transistor substrate. After the liquid crystal display panel is polished, the protecting member is removed from the thin-film transistor substrate.

What is claimed is:  
     
         1 . A method for polishing a liquid crystal display panel, wherein the liquid crystal display panel is provided with a thin-film transistor substrate having a pad area thereon, and the method comprises: 
 (a) providing a protecting member;    (b) bonding the protecting member on the pad area of the thin-film transistor substrate;    (c) polishing the liquid crystal display panel; and    (d) removing the protecting member from the thin-film transistor substrate.    
     
     
         2 . The method as claimed in  claim 1 , wherein the protecting member consists of plural layers, and the layer, being in contact with the pad area, is provided with electric conductivity.  
     
     
         3 . The method as claimed in  claim 1 , wherein the pad area comprises a gate pad area and a data pad area, and the protecting member, bonded on the gate pad area, and the protecting member, bonded on the data pad area, are contiguous.  
     
     
         4 . The method as claimed in  claim 1 , wherein the pad area comprises a gate pad area and a data pad area, and the protecting member, bonded on the gate pad area, and the protecting member, bonded on the data pad area, are not contiguous.  
     
     
         5 . A method for polishing a liquid crystal display panel, wherein the liquid crystal display panel comprises a thin-film transistor substrate, having a pad area thereon, and a color filter substrate, and the method comprises: 
 (a) cutting the liquid crystal display panel into a predetermined size;    (b) filling liquid crystal into the liquid crystal display panel and sealing the liquid crystal within the liquid crystal display panel;    (c) providing a protecting member;    (d) bonding the protecting member on the pad area of the thin-film transistor substrate;    (e) polishing the liquid crystal display panel; and    (f) removing the protecting member from the thin-film transistor substrate.    
     
     
         6 . The method as claimed in  claim 5 , wherein the protecting member consists of plural layers, and the layer, in contact with the pad area, is provided with electric conductivity.  
     
     
         7 . The method as claimed in  claim 5 , wherein the pad area comprises a gate pad area and a data pad area, and the protecting member bonded on the gate pad area and the protecting member bonded on the data pad area are contiguous.  
     
     
         8 . The method as claimed in  claim 5 , wherein the pad area comprises a gate pad area and a data pad area, and the protecting member bonded on the gate pad area and the protecting member bonded on the data pad area are not contiguous.
