Abstract:
The present invention addresses the problem of providing a transparent product which has an anti-glare surface having a surface shape which makes it possible to lower the haze value thereof and to obtain an excellent glare-suppressing effect. The transparent product has a transparent substrate 11 equipped with an anti-glare surface. The surface shape of the anti-glare surface is shaped in a manner such that the ratio (r0/r0.2) of the autocorrelation length (r0), which is the minimum value of the distance r at which the autocorrelation function g(r) represented by formula (1) is 0, to the autocorrelation length (r0.2), which is the minimum value of the distance r at which the autocorrelation function g(r) is 0.2, is 2 or higher. The autocorrelation function g(r) is obtained by converting the autocorrelation function g(tx, ty) obtained by normalizing the surface shape z(x, y) of the antiglare surface to polar coordinates (tx=r cos Φ, ty=r sin Φ), and averaging the angle direction.
