Abstract

An optical film includes light absorption anisotropic layers containing a dichroic substance, and at least one interlayer disposed between the light absorption anisotropic layers, in which all of the light absorption anisotropic layers have an absorption axis parallel to a thickness direction, thicknesses of the light absorption anisotropic layers are all 3.0 μm or less, a total thickness of the light absorption anisotropic layers is 4.0 μm or more, a total value calculated by multiplying a ratio of a content of the dichroic substance with respect to a mass of the light absorption anisotropic layer by the thickness of the light absorption anisotropic layer is 1.10 μm or more, and the interlayer is a layer in which an in-plane retardation at a wavelength of 550 nm is 25 nm or less and an absolute value of a thickness-direction retardation at the wavelength of 550 nm is 25 nm or less.
