Abstract
There is provided an antiglare hard-coated film that can maintain antiglare properties and suppress a reduction in the display contrast of a display, when composed of a transparent plastic film substrate and an antiglare hard coat layer formed thereon. The antiglare hard-coated filmincludes a transparent film substrateand a hard coat layerthat is provided on at least one side of the transparent film substrate, contains fine particles, and has an irregular surface, wherein the fine particleshave an average particle size of 6 μm to 15 μm and form irregularities with an average slope angle θa of 0.4° to 1.5°, and the antiglare hard-coated film satisfies the relation: {(the contrast ratio)/(the contrast ratio of a hard-coated film without the fine particles)}×100≧60%.
