PROBLEM TO BE SOLVED: To provide an optical film bonding device and method that bonds an optical film with increased efficiency.SOLUTION: The optical film bonding device continuously bonds an optical film to a substrate, using a strip-shaped master optical film 1 wound into a roll. The strip-shaped master optical film 1 has width nearly twice that corresponds to the substrate 10, the optical film bonding device is provided with: a transfer roller 6 that spools out the strip-shaped master optical film 1 in the long direction thereof; a cutting means 8 that cuts the spooled-out strip-shaped master optical film 1, in the long direction thereof, into a first strip-shaped optical film 4, having a width equal to that of the substrate 10, and a second strip-shaped optical film 5; a bonding roller 11 that bonds the first strip-shaped optical film 4 to the substrate 10; and a transfer roller 7 that takes up the second strip-shaped optical film 5. |
