Provided is a light absorption anisotropic film which is high in dichroism.
A light absorption anisotropic film, wherein content of a liquid crystalline non-colorable low molecular weight compound is 30% by mass or less; and which is obtained by fixing the alignment of a dichroic dye composition comprising at least one type of azo-based dichroic dye having nematic liquid crystallinity; and shows a diffraction peak derived from a periodic structure in a direction parallel to the alignment axis on measurement of X-ray diffraction.
本发明提供了一种具有高二色性的光吸收各向异性薄膜。
一种光吸收各向异性薄膜,其中液晶状不可着色的低分子量化合物的含量为 30% 或更少(按质量计);该薄膜是通过固定由至少一种具有向列液晶性的偶氮基二色性
染料组成的二色性
染料组合物的排列方式而获得的;在 X 射线衍射测量中,该薄膜在平行于排列轴的方向上显示由周期性结构衍生的衍射峰。
