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。

A liquid crystal display device, being widely used in the fields such as electronic tags, electronic papers, business cards and flexible display screens or the like, and a driving method for the liquid crystal display device. The liquid crystal display device has an upper substrate, a lower substrate and one or more layers of an encapsulated liquid crystal sandwiched between the upper substrate and the lower substrate. The layers of the encapsulated liquid crystal include two different liquid crystal microcapsules uniformly mixed. Combined with a driving method of a combination of high-low voltage and high-low temperature, a color display effect of high contrast and repeatable writing can be achieved.
