Abstract
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. The light absorption anisotropic film is high in dichroism.
