Abstract
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 an arithmetic average surface roughness Ra (μm) that is defined in JIS B 0601 (1994 version) is in the range of 0.05 to 0.15 μm in an uneven shape of a surface of the hard-coating antiglare layer, and the 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.
