ABSTRACT:
Laser etching is used to form channels which divides a conductive film adhered on a board of a touch panel into a plurality of regions of desired form. A conductive film damage preventing element is attached on the board of the moving-side panel of a pair of panels or the double-faced tape to join them at their perimeters, to prevent damage by the edge of the double-faced tape. A re-usable adhesive layer having 90-degree peel off power of 5 g to 500 g/25 mm is used to adhere optical material on a surface of the panel.
