Antiglare film and transmissive liquid crystal display
Abstract:
An antiglare film satisfies both (1) high antiglare property in the front direction and (2) absence of white blurring. One embodiment of the invention is an antiglare film provided with an antiglare layer on a transparent substrate, wherein the antiglare layer has a rugged structure on the surface opposite to the transparent substrate; the 5° reflectance of the antiglare film surface on the antiglare layer side is in a range of from 0.30% to 0.70%; the antiglare film surface on the antiglare layer side is provided with a rugged structure having arithmetic average roughness (Ra1) in the range of from 0.020 μm to 0.040 μm when a cutoff wavelength (λC) is 0.008 mm; and the antiglare film surface on the antiglare layer side is provided with a rugged structure having arithmetic average roughness (Ra2) in the range of from 0.35 μm to 0.45 μm when a cutoff wavelength (λC) is 0.8 mm.
