1. An anti-glare antireflection member comprising:
an anti-glare layer, and
a low refractive index layer on a substrate,
wherein the low refractive index layer comprises a binder resin, hollow particles and non-hollow particles,
wherein the substrate is a plastic film having an average erosion ratio from a surface to a depth of 20 μm of 1.4 μm/g or more, and
wherein an average of Δd is 7.0 nm or more and 40.0 nm or less, where Δd is a thickness difference of the low refractive index layer in an arbitrary 2 mm×2 mm region of the anti-glare antireflection member.
