Abstract
(EN)
Provided is an anti-glare film in which reflection is suppressed. An anti-glare film (10) in which an anti-glare layer (B) (12) is layered on a light-transmitting substrate (A), the anti-glare film being characterized in that recesses and projections are formed on the outermost surface on the anti-glare layer (B) (12) side of the anti-glare film (10), and the recesses and projections satisfy numerical expressions (1) and (2). (1): Ry ≥ 1. (2): θa ≥ 0.7. In numerical expression (1), Ry is the maximum height [µm] of the projecting parts of the recesses and projections, and in numerical expression (2), θa is the average inclination angle [°] of the recesses and projections.

L'invention concerne un film antireflet dans lequel la réflexion est suprimée. Un film antireflet (10) dans lequel une couche antireflet (B) (12) est appliquée en couches sur un substrat transmettant la lumière (A), le film antireflet étant caractérisé en ce que des évidements et des saillies sont formés sur la surface la plus à l'extérieur sur le côté couche antireflet (12) du film antireflet (10), et les évidements et les saillies satisfont les expressions numériques (1) et (2). (1) : Ry ≥ 1. (2) : θa ≥ 0.7. Dans l'expression numérique (1), Ry est la hauteur maximale [µm] des parties en saillie des évidements et des saillies, et dans l'expression numérique (2), θa est l'angle d'inclinaison moyen [°] des évidements et des saillies.
