    Abstract: Provided is an anisotropic optical film, which can, while keeping excellent display characteristics (e.g., brightness and contrast) in the direction of a viewing angle, suppress decreased display characteristics in the other directions, when the anisotropic optical film is used as a diffusion film of a display panel.In an anisotropic optical film including two or more anisotropic light diffusion layers where the linear transmittance varies depending on the incident angle of incident light, each of the anisotropic light diffusion layers is provided with a matrix region and a plurality of pillar regions that differ in refractive index from the matrix region, the film includes, as the anisotropic light diffusion layers, at least two types of anisotropic light diffusion layers (a) and (b) that differ in linear transmittance, the maximum linear transmittance of the anisotropic light diffusion (a) is 40% or more and less than 95%, and the minimum linear transmittance thereof is less than 20%, and the maximum linear transmittance of the anisotropic light diffusion layer (h) is 20% or more and less than 40%, and the minimum linear transmittance thereof is less than 20%.

    Abstract: Provided is a display apparatus which has a sufficient luminance even when viewed at a large viewing angle, and which can overcome a problem of color change. The display apparatus is a display apparatus including a display device showing a color change in accordance with viewer's viewing angle, and an anisotropic optical film having a diffusing property changed in accordance with the incident angle of light radiated thereinto. The anisotropic optical film has at least one scattering central axis, and an angle made between the scattering central axis and a direction along which the display device shows a minimum color change is from 20 to 65°, or −20 to −65°.

    Abstract translation: 提供即使在大视角观看时也具有足够的亮度的显示装置，并且能够克服颜色变化的问题。 显示装置是包括根据观察者的视角显示颜色变化的显示装置的显示装置和具有根据照射到其中的光的入射角度而改变的漫射特性的各向异性光学膜。 各向异性光学膜具有至少一个散射中心轴，并且在散射中心轴与显示装置显示最小颜色变化的方向之间形成的角度为20°至65°或-20°至-65°。
