  • Patent number: 9427894
    Abstract: Provided is an inexpensive anti-reflection article with a sufficient anti-reflection property by using an anti-reflection article manufacturing mold plate manufactured at low cost. In a method of manufacturing an anti-reflection article manufacturing mold plate used to manufacture an anti-reflection article provided with an anti-reflection surface in which minute convex portions or minute concave portions are densely arranged and a gap between the adjacent minute convex portions or minute concave portions is the shortest wavelength or less of a wavelength band for anti-reflection, the method of manufacturing an anti-reflection article manufacturing mold plate includes: molding an uneven shape on a surface of a receptive layer by causing an anti-reflection surface of another anti-reflection article to come into pressure-contact with the surface of the receptive layer including a curable base; and curing the receptive layer in which the uneven shape is molded.
    Type: Grant

  • Patent number: 9158040
    Abstract: To provide an anti-reflection article which can be manufactured by using an anti-reflection article manufacturing mold plate having improved abrasion resistance compared to the related art and has a sufficient anti-reflection property. An anti-reflection article is formed as an anti-reflection article in which minute concave portions are densely arranged and the gap between the adjacent minute concave portions is the shortest wavelength of a wavelength band or less of an electromagnetic wave for anti-reflection. In the anti-reflection article, at least some of the minute concave portions are a minute concave portion with multiple lowermost points in the minute concave portion.
