Claim Text:
1. A hard-coated antiglare film, comprising: a transparent plastic film substrate; and a hard-coating antiglare layer containing fine particles, on at least one surface of the transparent plastic film substrate, wherein the amount of fine particles is in the range of 10 to 20 parts by weight, per 100 parts by weight of a material for forming a hard-coating layer, the hard-coated antiglare film has a total haze value Ht in a range of 10% to 35%, the total haze value Ht and an internal haze value Hin satisfy an relationship expressed by the following formula (1), a surface of the hard-coating antiglare layer has an uneven shape and the following arithmetic average surface roughness Ra in a range of 0.1 to 0.3 μm, and the hard-coated antiglare film includes: convexities that exceed a roughness mean line of a surface roughness profile; no convexities in which line segments of portions of the mean line that cross the convexities each have length of 80 μm or longer; convexities that exceed a standard line that is in parallel with the mean line and is located at a height of 0.1 μm; and at least 50 convexities in which line segments of portions of the standard line that cross the convexities each have a length of 20 μm or shorter in a 4-mm long portion at an arbitrary location of the surface of the hard-coating antiglare layer, Total haze value Ht: a haze value (cloudiness) (%) of an entire hard-coated antiglare film, according to JIS K 7136 (2000 version), Internal haze value Hin: a haze value (%) of the entire hard-coated antiglare film measured in the case where a surface of the hard-coated antiglare film is smooth, Ra: an arithmetic average surface roughness (μm) defined in JIS B 0601 (1994 version).
