Adhesive film

Abstract

The adhesive film includes a film-like adhesive layer, a light release separator and a heavy release separator that are laminated on either side of the adhesive layer, and a carrier film further laminated on the heavy release separator. The outer edges of the light release separator and the carrier film forming the outer layer extend outward beyond the outer edge of the adhesive layer and the heavy release separator forming the inner layer. The outer edge sections of the adhesive layer are thereby protected. The outer edge section of the carrier film is gripped and released first, after which the outer edge section of the light release separator is gripped and released, and finally the heavy release separator is released, thereby allowing each separator and the carrier film to be reliably and easily released in the prescribed order.

What is claimed is: 
     
         1 . A method of making a display, comprising:
 providing an adhesive film and two adherends, the adhesive film comprising:   an adhesive layer;   first and second base material layers laminated in a manner sandwiching the adhesive layer; and   a carrier layer further laminated on the second base material layer, the carrier layer being in direct contact with the second base material layer;   wherein the first base material layer and the carrier layer are at opposite sides of the adhesive layer; and   wherein the outer edges of the first base material layer and the carrier layer extend outward beyond the outer edges of the adhesive layer and the second base material layer;   releasing the carrier layer;   after releasing the carrier layer, releasing the first base material layer;   after releasing the first base material layer, attaching the adhesive layer to one adherend of the two adherends;   after attaching the adhesive layer to the one adherend, releasing the second base material layer from the adhesive layer; and   thereafter, attaching the adhesive layer to the other adherend of the two adherends, such that the adhesive layer is disposed between the two adherends.   
     
     
         2 . The method according to  claim 1 , wherein the outer edge of the second base material layer is essentially flush with the outer edge of the adhesive layer. 
     
     
         3 . The method according to  claim 1 , wherein the outer edge of the carrier layer extends outward beyond the outer edge of the first base material layer. 
     
     
         4 . The method according to  claim 1 , wherein the peel strength between the first base material layer and the adhesive layer is lower than the peel strength between the second base material layer and the adhesive layer. 
     
     
         5 . The method according to  claim 1 , wherein the peel strength between the second base material layer and the carrier layer is lower than the peel strength between the second base material layer and the adhesive layer.
