Optical film cutting method, and optical film |
| abstract |
This invention relates to an optical film cutting method, which includes: a laser beam generation step of performing a waveform shaping of a laser beam to generate a laser beam having a rectangular waveform, and a cutting step of irradiating an optical film with the laser beam obtained by the laser beam generation step and having a rectangular waveform to thereby cut the optical film; as well as to an optical film that is cut by the cutting method and having a size of a raised part generated on a cutting surface thereof of 30 µm or less. According to the optical film cutting method of this invention, it is possible to provide an optical film cutting method for cutting an optical film such as a polarizing film by not using a gaussian beam but using a laser beam of which a waveform is shaped into a rectangular waveform, which is capable of maintaining a raised part size as small as possible in a cutting surface of the optical film and preventing generation of bonding defect and optical defect when the optical film is incorporated into various optical panels. |
