Document Type and Number:
WIPO Patent Application WO/2020/246314
Kind Code:
A1
Abstract:
Provided is an anti-glare film capable of suppressing glare on various display devices having different distances between a display element and an anti-glare layer. The anti-glare film comprises an anti-glare layer, and the anti-glare layer comprises a 500 μm² region that satisfies conditions 1 and 2 when the surface roughness of the 500 μm² region is measured, in which P is a maximum peak height, a first reference plane is a plane at a height obtained by adding P/6 to the average height, N1 is the number of peaks rising above the first reference plane, a second reference plane is a plane at a height obtained by adding P/3 to the average height, and N2 is the number of peaks rising above the second reference plane. P is 0.20 μm to 1.20 μm, inclusive 0.20 ≤ N2/N1 ≤ 0.45
