Liquid crystal display device

Abstract

A liquid crystal display (LCD) device using the COA process. The LCD device includes a passivation layer formed on metal wires in the wire-collecting area for preventing metal wires from exposure. Or, the LCD device includes an insulation layer formed between outer leads in the outer lead bonding (OLB) area for improving insulation among the outer leads.

       10 . The LCD device according to  claim 9 , wherein the insulation layer is the black matrix layer formed both in the BM area and between the outer leads in the OLB area.  
   
   
       11 . The LCD device according to  claim 10 , wherein said insulation layer is an organic resin material.  
   
   
       12 . The LCD device according to  claim 9 , wherein said insulation layer is a color filter layer.  
   
   
       13 . The LCD device according to  claim 9 , wherein the height of said insulation layer is lower than the height of said outer leads.  
   
   
       14 . The LCD device according to  claim 13 , wherein the height of said insulation layer is from about 0.5 micron to about 3 micron.  
   
   
       15 . A liquid crystal display (LCD) device, comprising: 
 an active area;    a black matrix (BM) area surrounding said active area, in which a black matrix layer is formed;    a wire-collecting area with a plurality of metal wires being adjacent to said BM area and connecting electrically with said active area;    an outer lead bonding (OLB) area with a plurality of outer leads being adjacent to and connecting electrically with said wire-collecting area; and    an insulation layer formed between the outer leads.    
   
   
       16 . The LCD device according to  claim 15 , wherein the insulation layer is the black matrix layer formed both in the BM area and between the outer leads in the OLB area.
