Abstract:
1. An antiglare film comprising: a transparent substrate; and an antiglare layer on the substrate, wherein concaves and convexes are formed in a surface of the layer; wherein ten-point mean roughness (Rz1) of the surface is 0.4-0.9 μm when a cutoff value is 0.8 mm and ten-point mean roughness (Rz2) of the surface is 0.02-0.06 μm when a cutoff value is 0.008 mm, wherein the ten-point mean roughness is determined as follows: a reference length is sampled from a roughness curve in the direction of its mean line; and the sum of the average value of absolute values of the heights of five highest profile peaks and the depths of five deepest profile valleys measured in the vertical magnification direction from the mean line of the sampled portion.
