Title (EN) ANTI-GLARE FILM
(FR) FILM ANTI-ÉBLOUISSEMENT
(JA) 防眩フィルム
Abstract:
(EN) This anti-glare film, which is attached to a surface of a display, is provided with an anti-glare layer with which: a glare value defined on the basis of the value of the standard deviation of the brightness distribution of the display in a state in which the anti-glare film is attached to the surface of the display is 10 or lower; the specular glossiness measured using 60 degree specular gloss is 40% or lower; and the transmitted image sharpness at an optical comb width of 0.5 mm is set to 40% or lower. Accordingly, glare of the display can be appropriately inhibited, and excellent anti-glare properties can be achieved.
(FR) Selon la présente invention, ledit film anti-éblouissement, lequel est fixé à une surface d'un dispositif d'affichage, est pourvu d'une couche anti-éblouissement grâce à laquelle : une valeur d'éblouissement définie sur la base de la valeur de l'écart-type de la distribution de luminosité du dispositif d'affichage dans un état dans lequel le film anti-éblouissement est fixé à la surface du dispositif d'affichage est inférieure ou égal à 10 ; la brillance spéculaire mesurée à l'aide d'un brillant spéculaire de 60 degrés est inférieure ou égale à 40 % ; et la netteté d'image transmise à une largeur de peigne optique de 0,5 mm est réglée à une valeur inférieure ou égale à 40 %. En conséquence, l'éblouissement de l'affichage peut être inhibé de manière appropriée, et d'excellentes propriétés anti-éblouissement peuvent être obtenues.
(JA) 防眩フィルムは、ディスプレイの表面に装着される防眩フィルムであって、ディスプレイの表面に装着した状態におけるディスプレイの輝度分布の標準偏差の値に基づき規定されるギラツキ値が10以下となる範囲の値であり、60度鏡面光沢で測定された鏡面光沢度が40%以下となる範囲の値であり、かつ光学櫛幅0.5mmの透過像鮮明度が40%以下となる範囲の値に設定された防眩層を備える。これによって、ディスプレイのギラツキを適切に抑制させると共に良好な防眩性を有することができる。
