Abstract: Provided is an antiglare film having a hard coat property, capable of highly suppressing generation of a rainbow interference pattern and interference fringes in display images, preventing white muddiness and scintillation of a display screen, while giving high contrast in a bright room and a dark room. The antiglare film includes an antiglare layer having an uneven form on its surface and formed on one face of a transparent substrate having an in-plane birefringence and a retardation of 3000 nm or higher. The antiglare layer contains silica fine particles, organic fine particles, and a binder resin. The silica particles include particles forming agglomerates to be contained coarsely and densely in the antiglare layer. The agglomerates are distributed densely around the organic fine particles, and some agglomerates adhere to surfaces of the organic particles and/or some silica particles are impregnated in the inside of the organic particles.
Abstract translation: 提供一种具有硬涂层性能的防眩膜，能够高度抑制彩虹干涉图案的产生和显示图像中的干涉条纹，防止显示屏幕的白色混浊和闪烁，同时在明亮的房间和暗室提供高对比度 。 防眩膜包括在其表面上具有凹凸形状的防眩层，并形成在具有面内双折射和3000nm以上的延迟的透明基板的一个面上。 防眩层含有二氧化硅微粒，有机微粒和粘结剂树脂。 二氧化硅颗粒包括形成聚集体的颗粒，其在防眩层中粗略且密集地包含。 附聚物密集地分布在有机细颗粒周围，并且一些附聚物附着到有机颗粒的表面和/或一些二氧化硅颗粒浸渍在有机颗粒的内部。
