Process and structure of liquid crystal panel with one drop fill

Abstract

This present invention relates to a process of liquid crystal panel with one drop fill (ODF). A black matrix, which can not be penetrated by an ultraviolet light while curing a sealant, is formed on the other substrate. Hence, in this present invention, it can avoid the aforementioned problem during the curing process and simplifies the curing process.

1 . A method for manufacturing a liquid crystal panel, comprising: 
 providing a first glass substrate;    forming a sealant, a black matrix and a plurality of color filters on a first surface of a second glass substrate, wherein said sealant is formed on the peripheral region of said second glass substrate without covering by said black matrix, said color filters are formed in a plurality of openings of said black matrix;    dropping an amount of liquid crystal on said first surface of said second glass substrate surrounded by said sealant;    assembling said first glass substrate and said second glass substrate, wherein said first surface of said first glass substrate faces said first surface of said second glass substrate; and    curing said sealant by a visible light.    
   
   
       2 . The method of  claim 1 , wherein the material of said sealant is acrylic resin.  
   
   
       3 . The method of  claim 1 , wherein the material of said sealant is the synthetic material of acrylic resin and epoxy resin.  
   
   
       4 . The method of  claim 1 , wherein said light is irradiated said sealant from a side of one of said glass substrates.  
   
   
       5 . The method of  claim 1 , wherein the material of said black matrix is selected from the group consisting of chromium, chromium oxide and an opaque resin.  
   
   
       6 . A liquid crystal panel, comprising: 
 a first glass substrate wherein a thin film transistor thereon;    a second glass substrate assembling with said first glass substrate by a sealant;    a liquid crystal layer disposed between said first glass substrate and said second glass substrate and surrounded by said sealant; and    a black matrix including a plurality of openings formed on a first surface of said first glass substrate, wherein said sealant is disposed on the peripheral region of a first surface of said second glass substrate.    
   
   
       7 . The liquid crystal panel of  claim 6 , further comprising a plurality of color filters formed on said first surface of said second glass substrate, wherein said color filters face said openings of said black matrix respectively.  
   
   
       8 . The liquid crystal panel of  claim 6 , further comprising a plurality of color filters formed in said openings of said black matrix on said first surface of said first glass substrate.  
   
   
       9 . The liquid crystal panel of  claim 6 , wherein said sealant is cured by a light irradiation.
