1. A head-mounted display comprising an anisotropic optical film whose linear transmittance changes depending on an incident light angle on a viewing side with respect to a color filter or an RGB light emitting layer in an organic electroluminescence display panel, wherein:
the anisotropic optical film includes at least a single-layered or multilayered anisotropic light diffusion layer;
the anisotropic light diffusion layer has a matrix region and a plurality of pillar regions having a refractive index different from that of the matrix region;
surface irregularities are formed in at least one outermost surface of the single-layered or multilayered anisotropic light diffusion layer; and
the surface irregularities have an arithmetic average roughness Ra of 0.10 μm or less, which is measured in accordance with JIS B0601-2001.
