Abstract | PROBLEM TO BE SOLVED: To provide a method of producing a heat setting optical film that enables an in-plane block state and an in-plane pass state for light normally incident to a plane of a film that functions as a linear polarizer.SOLUTION: A method of producing a heat setting optical film 32 having a linear polarizer function includes providing an apparatus with a film 32 comprising a polymeric material capable of developing birefringence; stretching the film 32 in a stretching region 66 to substantially uniaxially orient the film; and then heat setting the oriented film 84. The polymeric material capable of developing birefringence is selected from among polyethylene naphthalate, polyethylene terephthalate, polypropylene and syndiotactic polystyrene.
【課題】直線偏光子として機能するフィルムの平面に垂直に入射する光に対して、面内ブロック状態及び面内通過状態をさせることができるヒートセット型光学フィルムの作製方法の提供。【解決手段】光学フィルム32を作製する方法は、複屈折を発現できる高分子材料を使用したフィルム32を、装置に供給し、フィルム32を延伸区域66にて延伸し、実質的に一軸配向させ、その後に、この配向フィルム84をヒートセットすることによりなる直線偏光子機能を有するヒートセット型光学フィルムの製造方法。前記高分子材料はポリエチレンナフタレート、ポリエチレンテレフタレート、ポリプロピレン及びシンジオタクチックポリスチレンから選択される複屈折を発現できる高分子材料からなる光学フィルム。【選択図】図10 |
