  • Publication number: 20220292838
    Abstract: A vehicular display apparatus includes an obtaining unit that obtains obstacle information serving as information relating to an obstacle that hinders advancing of a preceding vehicle, and a display that displays the obstacle information in a situation where an own vehicle is stopped or is moving slowly, and the preceding vehicle is stopped or is moving slowly. The vehicular display apparatus displays a virtual image of the obstacle information, for example, in a case where the own vehicle is a first vehicle located on this side of an intersection, and the preceding vehicle is located on the other side of the intersection.

  • Patent number: 8419955
    Abstract: An antireflection structure that can be formed in a desired shape, and a method for manufacturing the same are provided. An antireflection structure 100 includes a resin layer 200 formed in a desired shape, and inorganic material fine particles 201 dispersed inside the resin layer. A plurality of fine concaves 202 having an average inner diameter shorter than or equal to the minimum wavelength of light whose reflection should be suppressed are formed at the surface of the antireflection structure 100, thereby reducing the equivalent refractive index at the surface of the resin layer 200. The fine concaves 202 are formed by, after forming a composite material in which the nanosized inorganic material fine particles 201 are dispersed in the resin layer, dissolving the inorganic material fine particles 201 dispersed at the surface of the resin layer 200, using a solvent that dissolves only the inorganic material fine particles 201.
