A hard-coated antiglare film that has superior antiglare properties, allow high definition to be provided even in the case of a low haze value, can prevent white blur in an oblique direction from occurring and, and can improve the depth of black in black display, as well as a polarizing plate, and the like. The hard-coated antiglare film includes a transparent plastic film substrate and a hard-coating antiglare layer containing fine particles, which is on at least one surface of the transparent plastic film substrate. The hard-coated antiglare film has a total haze value Ht in the range of 10% to 35%. The total haze value Ht and an internal haze value Hin satisfy a relationship of 0.5≦Hin/Ht≦0.9. The surface of the hard-coating antiglare layer has an uneven shape and an arithmetic average surface roughness Ra in the range of 0.1 to 0.3 μm.
