Title:
LIGHT ABSORPTION ANISOTROPIC FILM, OPTICAL FILM, AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/270199
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a light absorption anisotropic film in which a region of high visibility and a region of low visibility are easily controlled when the film is applied in an image display device, and viewing angle controllability is superior. The present invention also addresses the problem of providing an optical film and an image display device. This light absorption anisotropic film includes a dichroic substance and a liquid crystal compound, the light absorption anisotropic film having a plurality of regions having different transmittance center axis directions in the in-plane direction of the light absorption anisotropic film, the angle θ formed by the transmittance center axis and the direction normal to the surface of the light absorption anisotropic film being in the range of 0-70° in each of the plurality of regions, and any of specific conditions 1 through 3 being satisfied.
