Title (EN) ANTI-GLARE FILM AND DISPLAY DEVICE USING SAME
(FR) FILM ANTIREFLET ET DISPOSITIF D'AFFICHAGE L'UTILISANT
(JA) 防眩フィルム及びそれを用いた表示装置
Abstract:
(EN) Provided is an anti-glare film that can suppress the glare of image light of an ultra-high definition display element having a pixel density of 300 ppi or greater, and can suppress a decrease in contrast. An anti-glare film having an anti-glare layer, the internal haze being 5.0-25.0% and the surface haze being 20.0% or less, wherein a three-dimensional arithmetic mean roughness Sa2.5-250 of the surface of the anti-glare layer when λs is 2.5 μm and λc is 250 μmm, and a three-dimensional arithmetic mean roughness Sa2.5-70 of the surface of the anti-glare layer when λs is 2.5 μm and λc is 70 μm, both satisfy the following equations (1)-(3). (1) 0.080 μm ≤ Sa2.5-250 (2) Sa2.5-250 - Sa2.5-70 ≤ 0.030 μm (3) 0.83 ≤ Sa2.5-70/Sa2.5-250
(FR) L'invention concerne un film antireflet qui peut supprimer l'éblouissement de la lumière d'image d'un élément d'affichage à ultra haute définition ayant une densité de pixel de 300 ppi ou plus, et peut supprimer une diminution du contraste. Un film antireflet ayant une couche antireflet, le trouble interne étant de 5,0 à 25,0 % et le trouble de surface étant de 20,0 % ou moins, une rugosité moyenne arithmétique tridimensionnelle Sa2,5-250 de la surface de la couche antireflet lorsque λs est de 2,5 µm et λc est de 250 µmm, et une rugosité moyenne arithmétique tridimensionnelle Sa2,5-70 de la surface de la couche antireflet lorsque λs est de 2,5 µm et λc est de 70 µm, les deux satisfont les équations suivantes (1)-(3). (1) 0,080 μm ≤ Sa2,5-250 (2) Sa2,5-250 - Sa2,5-70 ≤ 0,030 μm (3) 0,83 ≤ Sa2,5-70/Sa2,5-250
(JA) 画素密度300ppi以上の超高精細の表示素子の映像光のギラツキを抑制でき、かつコントラストの低下を抑制できる防眩フィルムを提供する。 防眩層を有する防眩フィルムであって、内部ヘイズが5.0~25.0%、表面ヘイズが20.0%以下であり、λs2.5μmかつλc250μmとした際の前記防眩層表面の三次元算術平均粗さSa2.5-250と、λs2.5μmかつλc70μmとした際の前記防眩層表面の三次元算術平均粗さSa2.5-70とが、下記式(1)~(3)を満たす、防眩フィルム。 0.080μm≦Sa2.5-250 (1) Sa2.5-250-Sa2.5-70≦0.030μm (2) 0.83≦Sa2.5-70/Sa2.5-250 (3)
