Abstract
(EN)
In order to achieve both an anti-glare effect and a sparkle-suppressing effect in a transparent article having an anti-glare surface having a recess and protrusion structure. The transparent article 10 has an anti-glare surface having a recess and protrusion structure. The recess and protrusion structure of the anti-glare surface 12a has a 6-20 μm cycle length d obtained from the autocorrelation function Gx (m).
(FR)
L’objectif de l’invention est d’obtenir à la fois un effet antireflet et un effet de suppression de scintillement dans un article transparent ayant une surface antireflet ayant une structure d’évidement et de saillie. La présente invention concerne un article transparent 10 qui comporte une surface antireflet ayant une structure d’évidement et de saillie. La structure d’évidement et de saillie de la surface antireflet 12a a une longueur de cycle d de 6-20 µm obtenue à partir de la fonction d’autocorrélation Gx (m).
(JA)
凹凸構造のアンチグレア面を有する透明物品に関して、防眩効果とスパークルを抑制する効果とを両立させる。透明物品10は、凹凸構造のアンチグレア面12aを有する。アンチグレア面12aの凹凸構造は、自己相関関数G(m)より求められる周期長さdが6~20μmである。
