    • PROBLEM TO BE SOLVED: To provide a manufacturing method of a liquid-crystal display panel having excellent display characteristics, with extremely high manufacturing efficiency using a simple manufacturing apparatus.SOLUTION: A long first optical film 100 comprises: a reflection polarization film having a reflection axis in a crosswise direction; and a polarizing film having an absorption axis in a crosswise direction. The long first optical film 100 is slit-processed at a width corresponding to one set of opposing sides of a liquid crystal cell 200. A second optical film 100' includes a polarizing film having an absorption axis in a longer direction and is slit processed at the width corresponding to the one set of opposing sides of the liquid crystal cell 200. A manufacturing method includes: a step of cutting the long first optical film 100 in a crosswise direction while drawing out the long first optical film 100 from a film roll 300 in a length corresponding to the other set of opposing sides thereof; a step of cutting the second optical film 100' in a crosswise direction while drawing out the second optical film 100' from a film roll 300' in a length corresponding to the other set of opposing sides thereof; a step of laminating the cut first optical film 100 on one surface of the liquid crystal cell 200; and a step of laminating the cut second optical film 100' on the other surface of the liquid crystal cell 200.
    • 要解决的问题:提供具有优异的显示特性的液晶显示面板的制造方法,使用简单的制造装置具有极高的制造效率。解决方案:长的第一光学膜100包括:具有反射的反射偏振膜 轴在横向上; 以及在横向上具有吸收轴的偏振膜。 长的第一光学膜100以对应于液晶单元200的一组相对侧的宽度进行狭缝处理。第二光学膜100'包括在较长方向上具有吸收轴的偏振膜,并且在 对应于液晶单元200的一组相对侧的宽度。一种制造方法包括:从薄膜辊300中拉出长的第一光学膜100的同时沿横向切割长的第一光学膜100的步骤 其长度对应于另一组相对侧; 同时从相对于另一组相对侧的长度的胶片卷300'中拉出第二光学膜100'而沿横向切割第二光学膜100'的步骤; 将切割的第一光学膜100层压在液晶单元200的一个表面上的步骤; 以及将切割的第二光学膜100'层压在液晶单元200的另一个表面上的步骤。
