HARD-COATED ANTIGLARE FILM, POLARIZING PLATE AND IMAGE DISPLAY INCLUDING THE SAME, AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a hard-coated antiglare film which has excellent antiglare properties and a low haze value, and can prevent a white blur from being generated.

SOLUTION: The hard-coated antiglare film has a total haze value Ht in a range of 10-35%. The total haze value Ht and an internal haze value Hin satisfy a relationship of 0.5≤Hin/Ht≤0.9. The surface of a hard-coat layer has an uneven shape and arithmetic average surface roughness Ra in the range of 0.1-0.3 μm. 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 lengths of ≥80 μm; convexities that exceed a standard line which is in parallel with the mean line and located at the height of 0.1 μm in a 4-mm long portion at an arbitrary location on the surface of the hard-coat layer; and at least 50 convexities in which line segments of portions of the standard line that cross the convexities have lengths of ≤20 μm in a 4-mm long portion at an arbitrary location on the surface of the hard-coat layer.
