Method for producing display device

Abstract

A method for producing a display device includes: (a) coating a resin composition on at least one of a display part and a protective part, (b) closely adhering the display and protective parts via a resin composition interposed therebetween, and (c) arranging the cured resin layer between the display and protective parts by curing the resin composition by irradiating UV rays on an external side of the protective part. If a defect is detected, the method includes: (d) separating the display and protective parts by applying a wire to a side face of the cured resin layer where the protective and display parts are bonded and moving the wire through the cured resin layer, (e) peeling off and removing the cured resin adhered to the separated display and protective parts by a removing solution which contains an organic solvent, and (f) repeating steps (a) to (c).

1 . A method for producing a display device, the display device comprising a display part for displaying an image and a light-transmitting protective part provided on the display part, a light-transmitting cured resin layer arranged between the display part and the protective part, the method comprising the steps of:
 (a) coating a resin composition, the resin composition comprising a raw material of the cured resin, on at least one of the display part and the protective part,   (b) adhering the display part and the protective part with the resin composition interposed therebetween, and   (c) arranging a cured resin layer between the display part and the protective part by curing the resin composition by irradiating UV rays on an external side of the protective part, the cured resin layer having a storage elastic modulus of less than 1.0×10 5  Pa; and   wherein the following additional steps (d) to ( 0  are performed to remove defects present in the display device:   (d) separating the display part and the protective part by applying a slack wire having a smaller diameter than a thickness of the cured resin layer at a side face of the cured resin layer where the protective part and the display part are bonded, and moving the slack wire through the cured resin layer,   (e) peeling off and removing the cured resin adhered to the separated display part and the protective part by a removing solution comprising at least one organic solvent, and   (f) repeating the steps (a) to (c).   
     
     
         2 . The method for producing a display device according to  claim 1 , wherein the at least one organic solvent is compatible when mixed with the resin composition before curing in a 1:1 volume ratio. 
     
     
         3 . The method for producing a display device according to  claim 1 , wherein the removing solution comprises limonene or toluene as the at least one organic solvent. 
     
     
         4 . The method for producing a display device according to  claim 3 , wherein when the at least one organic solvent is limonene, the removing solution further comprises ethyl alcohol or isopropyl alcohol. 
     
     
         5 . The method for producing a display device according to  claim 1 , wherein the protective part is formed of a polymer material, and the removing solution comprises limonene as the at least one organic solvent. 
     
     
         6 . The method for producing a display device according to  claim 1 , wherein the display device is a liquid crystal display device in which a polarizing plate is provided on a surface of the display part.
