Abstract
An anti-glare member prevents reflection of external light by surfaces of displays or screens without causing reduction of contrast and glare of displayed images. The anti-glare member has an anti-glare layer comprising microparticles and a transparent binder wherein the microparticles are black microparticles having a value (n), obtained by dividing absolute value of complex index of refraction of the black microparticles by index of refraction of the transparent binder, of 0.95 to 1.05. The arithmetical mean roughness (Ra) according to JIS B0601:2001 of surface of the anti-glare layer is 0.3 to 1.0 μm.
