To provide an antiglare film which exhibits excellent display characteristics combining antiglare properties and prevention of white blurring and which can prevent occurrence of protrusions on a surface of an antiglare layer to enhance yield of products, the protrusions being causative of appearance defect.SOLUTION: An antiglare film has an antiglare layer on at least one surface of a light-transmitting substrate. The antiglare layer is formed using antiglare layer forming material which comprises resin, particles, and a thixotropic imparting agent. The antiglare layer has agglomerate portions which are formed by agglomeration of the particles and the thixotropic imparting agent and which form convex parts on the surface of the antiglare layer. In the agglomerate portions which form the convex parts, the plurality of the particles lie gathered in a plane direction of the antiglare layer.SELECTED DRAWING: Figure 1 【課題】防眩性と、白ボケの防止とを両立した優れた表示特性を有するとともに、外観欠点となる防眩層表面の突起状物の発生を防止して製品の歩留まりを向上させた防眩性フィルムを提供する。【解決手段】透光性基材の少なくとも一方の面に、防眩層を有する防眩性フィルムであって、前記防眩層が、樹脂、粒子およびチキソトロピー付与剤を含む防眩層形成材料を用いて形成されており、前記防眩層が、前記粒子および前記チキソトロピー付与剤が凝集することによって、前記防眩層の表面に凸状部を形成する凝集部を有しており、前記凸状部を形成する凝集部において、前記粒子が、前記防眩層の面方向に、複数集まった状態で存在する。【選択図】 図１
