Document Type and Number:
WIPO Patent Application WO/2024/048193
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a light-absorbing anisotropic film that exhibits excellent tightness of black when used in an image display device, a manufacturing method thereof, and a laminate and an image display device having the light-absorbing anisotropic film. The light-absorbing anisotropic film of the present invention comprises a dichroic substance and a liquid crystal compound, at least a part of the dichroic substance forms an array structure, and where an average value of the length of the long axis of the array structure observed in a region A from one surface to 150 nm in the film thickness direction in a cross section observed with a scanning transmission electron microscope is denoted by Ltop, and an average value of the length of the long axis of the array structure observed in a region B from the other surface to 150 nm in the film thickness direction is denoted by Llow, the following formula (1-1) and/or formula (1-2) is satisfied. Ltop ≤ 35 nm (1-1) Llow ≤ 35 nm (1-2)
