OPTICAL FILM WITH PRESSURE SENSITIVE ADHESIVE ON BOTH SIDES AND METHOD FOR PRODUCING IMAGE DISPLAY DEVICE USING THEREOF, AND METHOD FOR SUPPRESSING CURL OF OPTICAL FILM WITH PRESSURE SENSITIVE ADHESIVE ON BOTH SIDES
OPTICAL FILM WITH PRESSURE SENSITIVE ADHESIVE ON BOTH SIDES AND METHOD FOR PRODUCING IMAGE DISPLAY DEVICE USING THEREOF, AND METHOD FOR SUPPRESSING CURL OF OPTICAL FILM WITH PRESSURE SENSITIVE ADHESIVE ON BOTH SIDES
The optical film with a pressure sensitive adhesive on both sides includes a first pressure sensitive adhesive layer having a thickness of 3 μm to 30 μm on first main surface of an optical film, and a second pressure sensitive adhesive layer having a thickness of 50 μm or more on second main surface of the optical film. A first protective sheet and a second protective sheet are releasably attached on the first pressure sensitive adhesive layer and the second pressure sensitive adhesive layer, respectively. The residual stress of the second pressure sensitive adhesive layer S2 (N/cm2), the thickness of the first protective sheet Y (μm); and the thickness of the second protective sheet Z (μm) satisfy the following relationship: 20≦Y≦80; 45≦Z; and Y+0.17 Z+10.6 S2≧63.
