Abstract
This head-mounted display is provided with, closer to the viewing side than a color filter having a black matrix between pixels in a liquid crystal display panel (), an anisotropic optical film (), the linear transmittance of which changes according to the angle of incident light, wherein the anisotropic optical film () includes a single-layered or multilayered anisotropic light diffusion layer, on at least on one surface of the anisotropic light diffusion layer, surface asperities having an arithmetic average roughness Ra of 0.10 μm or less, which is measured in accordance with JIS B0601-2001, are formed, 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, and the visibility of the black matrix is lowered by the anisotropic optical film (), thereby making it possible to obtain a higher sense of immersion without feeling coloring.
