    • The present invention relates to a method for producing an optical film, the optical film having the same molecule length in X-axis, Y-axis and Z-axis orientation, comprising the steps of: stretching the optical film along the X-axis; fixing the length of the optical film along the Y-axis; heating the optical film to above an extension temperature; shrinking the optical film along the X-axis; stretching the optical film along the Z-axis; and enabling the molecule length of the optical film along the X-axis to be longer than that along the Z-axis while the molecule length of the optical film along the Z-axis is longer than that along the Y-axis.
    • 本发明涉及一种光学膜的制造方法,该光学膜具有X轴,Y轴和Z轴取向具有相同的分子长度,其特征在于,包括以下步骤:沿X轴拉伸光学膜; 沿着Y轴固定光学膜的长度; 将光学膜加热至延伸温度以上; 沿X轴收缩光学膜; 沿Z轴拉伸光学膜; 并且使光学膜沿X轴的分子长度比沿着Z轴的光学膜的分子长度长,而沿着Z轴的光学膜的分子长度比沿着Y轴的分子长度长。
