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 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.
