Abstract
Provided is an anti-glare antireflection member capable of suppressing coloring in viewing in an oblique direction, and suppressing visual recognition of local luminescent spots. The anti-glare antireflection member comprises an anti-glare layer and a low refractive index layer on a substrate. The 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 anti refractive index layer.
