Abstract:
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 a thickness of said hard-coating antiglare layer is in the range of 8 to 12 μm, a surface of said hard-coating antiglare layer containing fine particles has an uneven shape and has an arithmetic average surface roughness Ra (μm) that is defined in JIS B 0601 (1994 version) in a range of 0.05 to 0.15 μm, and said hard-coated antiglare film includes at least 80 convexities that exceed a roughness mean line of a surface roughness profile in a 4-mm long portion at an arbitrary location of the surface of the hard-coating antiglare layer, and the hard-coated antiglare film includes convexities exceeding a standard line that is in parallel with the roughness mean line of the surface roughness profile and is located at a height of 0.1 μm and includes at least 50 of the 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 the 4-mm long portion at an arbitrary location of the surface of the hard-coating antiglare layer but does not include any convexities in which the line segments each have a length of 50 μm or longer.
