Abstract
Provided is a polarizing film showing high dichroism comprising a substrate, and a photo alignment film and a light absorption anisotropic film laminated on the substrate in this order. The light absorption anisotropic film is obtained by fixing the alignment of a dichroic dye composition comprising at least one nematic liquid crystalline azo dichroic dye and in X-ray diffraction measurement thereof, diffraction peaks derived from periodic structure along a vertical direction to the alignment axis are present, the period indicated by at least one of the diffraction peaks is 3.0 to 15.0 Å and an intensity of the diffraction peak does not show a maximum value in the range of ±70° of the film normal line direction in a plane vertical to the alignment axis.
