Abstract: A clay dispersion, wherein an organically modified clay is dispersed in a polar organic solvent, and the clay dispersion is obtained by: dispersing a swelling clay in a liquid which includes water as a main component; adding organic onium ions to the liquid to cause ion-exchange between the organic onium ions and hydrophilic cations existing on the surface of the swelling clay to obtain an organically modified clay; removing the ion-exchanged hydrophilic cation to obtain the organically modified clay which is in a condition that water exists in the clay; and adding the organically modified clay from which the ion-exchanged hydrophilic cation is removed to an polar organic solvent.

Abstract: To provide an inorganic fiber sheet with high workability, which is also excellent in tackiness or adhesiveness when a pressure-sensitive adhesive or an adhesive has been applied thereto. The inorganic fiber sheet is a non-woven fabric containing inorganic fibers. The inorganic fiber sheet has a thickness T of 1 mm or more and contains shots derived from inorganic fibers and having a diameter of 45 μm or more. The shots included in the inorganic fiber sheet is distributed in a sheet thickness direction as represented by Formula 1. Provided that Formula 1 is “1−Y/X≤ 0.11”, where X represents “a total weight of the shots in the inorganic fiber sheet per unit area “/” a total weight of the inorganic fiber sheet per unit area”, and Y represents “a weight of the shots per unit area included in the inorganic fiber sheet from which a portion having a thickness t and satisfying 0≤t≤s is removed, provided, however, that 0.10 mm≤s≤0.55 mm, with a wire side surface of the inorganic fiber sheet as a reference surface “/” a weight per unit area of the inorganic fiber sheet from which the portion having the thickness t is removed with the wire side surface of the inorganic fiber sheet as the reference surface”.

Abstract: To provide a head-mounted display that can obtain a higher sense of immersion without sensing coloring by diffusing and transmitting light from an organic electroluminescence display panel by an anisotropic optical film to reduce the visibility of a black matrix (BM). The head-mounted display is provided with an anisotropic optical film on the viewing side with respect to a color filter or an RGB light emitting layer in an organic electroluminescence display panel, said anisotropic optical film having a linear transmittance that varies depending on an incident light angle. The head-mounted display is characterized in that: the anisotropic optical film includes at least a single or a plurality of anisotropic light diffusion layers; and the anisotropic light diffusion layers have a matrix region and a plurality of pillar regions having refractive indexes different from that of the matrix region.
