Abstract:
Provided is an anti-glare film excellent in anti-glare properties and capable of suppressing reflected scattered light. The anti-glare film includes an anti-glare layer, the anti-glare film having an uneven surface, wherein for an amplitude spectrum of elevation of the uneven surface, when a sum of amplitudes corresponding to spatial frequencies of 0.005 μm−1, 0.010 μm−1, and 0.015 μm−1 is defined as AM1 and an amplitude at a spatial frequency of 0.300 μm−1 is defined as AM2, AM1 is 0.070 μm or more and 0.400 μm or less, AM2 is 0.0050 μm or more, and AM2
