POLARIZING PLATE, IMAGE DISPLAY DEVICE, AND PRODUCTION METHOD OF ANTIGLARE FILM

PROBLEM TO BE SOLVED: To provide an antiglare film giving a high contrast and suppressing glare.SOLUTION: The antiglare film has an antiglare layer formed of a composition comprising at least (A) a curable resin compound and (B) light-transmitting particles on a transparent support body. A value obtained by dividing a film thickness of the antiglare layer by an average particle diameter of the (B) light-transmitting particles is 1.1 to 3.0; the antiglare film has a total haze value of 0.5 to 5.0% and an inner haze value of 1.5% or less; and an upper uneven distribution rate represented by the following formula relating to the (B) light-transmitting particles in the antiglare layer is 45% to 99%. The upper uneven distribution rate (%) is defined, with respect to the layer formed of the composition comprising the (A) and (B) components, by [number of the (B) component present in a film thickness region occupying 50% of the film thickness from the central of the layer to the opposite side to the transparent support body]/[whole number of the (B) component present in the whole layer formed of the composition comprising the (A) and (B) components]×100. 【課題】高コントラストでかつギラツキが抑制された防眩フィルムを提供すること。【解決手段】透明支持体上に、少なくとも（Ａ）硬化性樹脂化合物及び（Ｂ）透光性粒子を含む組成物から形成される防眩性層を有する防眩フィルムであって、前記防眩性層の膜厚を前記（Ｂ）透光性樹脂粒子の平均粒径で除した値が１．１〜３．０であり、前記防眩フィルムの全ヘイズ値が０．５〜５．０％、内部へイズ値が１．５％以下であって、前記（Ｂ）透光性粒子の前記防眩層内における下記式で表される上部偏在率が４５％〜９９％である防眩フィルム。上部偏在率＝［（Ａ）及び（Ｂ）の成分を含む組成物から形成される層の膜厚方向において、層の中央から透明支持体とは反対側５０％の膜厚領域に存在する（Ｂ）成分の個数］?［（Ａ）及び（Ｂ）の成分を含む組成物から形成される層全体に存在する（Ｂ）成分の総数］?１００（％）【選択図】なし
