In the manufacture of liquid crystal displays, these films are stripped of the release film and bonded to a liquid crystal cell glass substrate through an adhesive layer. ^ In addition, there may be a case where a pressure-sensitive adhesive layer is attached to a decorative film, a film is attached thereto, and a protective film is attached to the other side of the film surface, and the product may be manufactured. When this decorative film is bonded to a substrate, the peeling film is removed and bonded through an adhesive layer. The optical film is cut into a single piece for use or finished. However, during processing, the polarizing film and the adhesive layer may peel off. For example, when the peeling film is peeled in order to attach the 5 light film to the glass substrate of the liquid crystal cell, the partial domain and the adhesive layer may peel and fall. In addition, through the adhesive layer, the "main: film is bonded to the glass substrate" when there are bubbles or wrinkles, at this time, sometimes the polarizing film needs to be peeled off, corrected, and then re-quoted ; ^ To stick this phen, the adhesive layer must be left on the polarizing film, and not on the glass 316654 200534013 glass substrate. Therefore, it is necessary to make the adhesive layer adhere more strongly to the polarizing film than to the glass substrate. As for the method of making the adhesive layer more strongly adhere to the polarizing plate or the retardation plate, there is a proposal to apply a corona treatment to the surface of the adhesive layer to the polarizing plate or the retardation plate. Treatment (refer to patent document Ran =, it is not enough to apply surface treatment only to the adhesive layer, but a method of tightly adhering the adhesive layer to the film is needed.
