Abstract: A tiling display is obtained by arranging a plurality of unit panels, each including an anti-reflective film-attached transparent substrate on a display surface side. The anti-reflective film-attached transparent substrate includes a transparent substrate, a diffusion layer, and an anti-reflective film in this order toward the display surface side, and two of the unit panels adjacent to each other satisfy the condition 1.

Abstract: An anti-reflective film-attached transparent substrate includes: a transparent substrate including two major surfaces; and a diffusion layer and an anti-reflective film on one major surface of the transparent substrate, which are provided in this order. (A) A luminous reflectance SCI Y of an outermost surface of the anti-reflective film-attached transparent substrate is 1% or lower. (B) The anti-reflective film has a lamination structure in which at least two dielectric layers having different refractive indices are laminated. (C) A ratio (SCE Y)/(SCI Y) of a diffuse reflectance SCE Y of the outermost surface of the anti-reflective film-attached transparent substrate to the luminous reflectance SCI Y of the outermost surface of the anti-reflective film-attached transparent substrate is 0.15 or higher.

Abstract: An anti-reflective film-attached transparent substrate includes: a transparent substrate comprising 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°, 25°, 45°, 75°, and 110° with respect to a specularly reflected light under a D65 light source satisfy formulas (1) −6≤a*≤2, (2) −1≤b*≤12 (3) b*≤−2a*+4, and (4) b*≥−2a*−5.
