摘要：
Provided is an anisotropic optical film which is capable of diffusing and condensing light in a wide incident angle range even when this film merely has a single anisotropic diffusion layer, which gives no unnatural impression, and which does not easily generate any light interference (rainbow).
An anisotropic optical film having a diffusing property which varies in accordance with the incident angle of light radiated thereinto. The film has rectangularly columnar region, and a matrix region. At an incident angle of the light at which a maximum linear transmittance is exhibited, the maximum linear transmittance is 30% or more and less than 95%; and at an incident angle of the light at which a minimum linear transmittance is exhibited, the minimum linear transmittance is 20% or less.

本发明提供一种各向异性光学膜，其即使在仅具有单一的各向异性扩散层的情况下也能够在宽的入射角范围内散射和聚光，因此不会产生不自然的印象，不容易产生光线干涉（彩虹） 。 具有根据照射的光的入射角而变化的扩散性的各向异性光学膜。 该膜具有矩形柱状区域和矩阵区域。 在显示最大线性透射率的光的入射角处，最大线性透射率为30％以上且小于95％; 并且在表现出最小线性透射率的光的入射角处，最小线性透射率为20％以下。
