Abstract: An anti-reflective film-attached transparent substrate includes: a transparent substrate having two main surfaces; and a diffusion layer and an anti-reflective film in this order from a transparent substrate side on one main surface of the transparent substrate. When reflection on the other main surface of the transparent substrate is eliminated and a light source is incident on the one main surface at an incident angle of 45°, a* and b* of diffusely reflected lights at angles of −15°, 15°, and 25° with respect to a specularly reflected light under a D65 light source satisfy formulas (1) −5≤a*≤−1 and (2) 0≤b*≤9.

Abstract: An antiglare layer-attached transparent substrate includes: a transparent substrate comprising two main surfaces; and an antiglare layer and an anti-reflective layer in this order on at least one main surface of the transparent substrate. The antiglare layer-attached transparent substrate has a haze value of 30% or more, and a skewness Ssk of 0.4 or less on a surface having the antiglare layer, and the antiglare layer contains fine particles, and a difference between a thickness of the antiglare layer and an average particle diameter of the fine particles is 4 μm or less.
