Abstract:
According to the invention, an optical film with adhesive on both sides comprises: an optical film including a polarizing plate; a first pressure sensitive adhesive layer provided on a surface of the optical film at a side configured to be bonded to an image display cell; and a second pressure sensitive adhesive layer provided on a surface of the optical film at a side configured to be bonded to a transparent plate or the touch panel. Further, a protective sheet is releasably attached on each of the first pressure sensitive adhesive layer and the second pressure sensitive adhesive layer. A thickness of the second pressure sensitive adhesive layer is preferably 30 μm or more. In a practical use, the optical film with adhesive on both sides according to the present invention is, for example, disposed between a front transparent plate or a touch panel and an image display cell.
