1. a hard-coated antiglare film, it is at least one face of transparent plastic film base material, to have the hard-coated antiglare film of the antiglare hardcoat that comprises particulate, it is characterized in that, the following arithmetic mean surface roughness Ra of the concaveconvex shape on antiglare hardcoat surface is the scope of 0.05~

  • 0.15 μ

    m, and in the scope that the length of the optional position on described antiglare hardcoat surface is 4mm, there is the convex shaped part of 80 above roughness average lines that surpass surface roughness profile;

    And, in the concaveconvex shape on described antiglare hardcoat surface, thering is the convex shaped part of the line that is above standard, the roughness average line of described standard lines and described surface roughness profile is parallel and be positioned at the height of 0.1 μ

    m;

    In the scope that the length of the optional position on described antiglare hardcoat surface is 4mm, described in the crosscut of described standard lines, the line segment length of the part of convex shaped part is that the described convex shaped part below 20 μ

    m is more than 50, and not comprising described line segment length is convex shaped parts more than 50 μ

    mThe arithmetic mean surface roughness of stipulating in the JIS B0601 of Ra;

    1994 version, its unit is μ

    m.
