Adjusting Apparatus of Gap Width and Method Thereof

Abstract

Provided is an adjusting method of a gap width of a laminated body composed of a color filter substrate and a TFT array substrate. A decompression chamber acting as a closed space communicating with a vacuum pump is decompressed, while a pressurization chamber that includes a decompression chamber is pressurized by driving a compressor.

1 . A manufacturing method of a display panel in which a display medium is sealed between a pair of substrates disposed opposite to each other, said substrates being separated from each other with a gap of a specified width, said method comprising the steps of:
 (a) coating sealant in the form of a picture frame on a peripheral portion of at least one of said pair of substrates except an injection port for said display medium;   (b) obtaining a laminated body having the gap of the specified width by laminating said pair of substrates with said sealant interposed therebetween;   (c) applying a pressure to said pair of substrates from the outside while decompressing said gap;   (d) curing said sealant; and   (e) injecting said display medium from said injection port after curing said sealant.   
   
   
       2 . The manufacturing method of a display panel according to  claim 1 , wherein in said step (c), the pressure applied from the outside is applied with a fluid taken as a pressure medium. 
   
   
       3 . The manufacturing method of a display panel according to  claim 1 , wherein in said steps (c) and (d), a curing process for said sealant is carried out after said decompressing process and said pressure applying process. 
   
   
       4 . The manufacturing method of a display panel according to  claim 1 , wherein in said step (c), the pressure in said gap is equal to the atmospheric pressure or lower.
