Title:
異方性光学フィルム
Document Type and Number:
Japanese Patent JP5670601
Kind Code:
B2
Abstract:
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.
