| titleOfInvention | Optical film manufacturing method and manufacturing apparatus |
| abstract | PROBLEM TO BE SOLVED: To produce an optical film by a melt casting film forming method, in which two unpolarized films are orthogonal to each other before the unstretched film sandwiched between a cooling roll and a touch roll is stretched. By passing between the plates, observing the transmitted light of the unstretched film in a crossed Nicol state, and confirming the presence or absence of casting streaks, the vertical streaks generated in the film in the next stretching step are An optical film manufacturing method and a manufacturing apparatus that can improve the productivity of the optical film are provided. An optical film manufacturing method includes passing an unstretched film between two polarizing plates orthogonal to each other before stretching the unstretched film in the machine direction and / or the transverse direction. And observing the transmitted light of the unstretched film in a crossed Nicols state. In the observation process before stretching, the transmitted light of the unstretched film is observed in a crossed nicols state, and by confirming the presence or absence of casting streaks, the vertical streaks generated in the film in the next stretching process are predicted in advance. To do. [Selection] Figure 1 |
