Optical film with adhesive on both sides and method for fabrication of image display device employing same

This optical film with adhesive on both sides comprises: an optical film, further comprising a polarizing sheet; a first adhesive layer which is disposed on a face of the optical film which is a side which is pasted upon an image display cell; and a second adhesive layer which is disposed on a face of the optical film which is a side which is pasted upon a transparent plate or a touch panel. The first adhesive layer and the second adhesive layer respectively have detachable protective sheets adhered thereupon. It would be desirable for the second adhesive layer to have a thickness of 30µm or more. This optical film with adhesive on both sides would be usable, as an example, positioned between the transparent plate or the touch panel and the image display cell.
