To provide an antidazzle film achieving both antidazzle property and scratch resistance.SOLUTION: The antidazzle film includes an antidazzle layer having a surface profile controlled to have a skewness Rsk of less than 0 and an average length RSm of roughness curve elements of 1 to 50 μm. The antidazzle layer preferably contains no particles having a particle diameter of equal to or greater than 3 μm, and more preferably, the antidazzle layer contains no particles. The antidazzle film may have a haze of 1 to 60%. The surface of the antidazzle layer may have a 60° gloss of 1 to 70%. The antidazzle layer may be a cured product of a curable composition containing a photocurable resin. The antidazzle film may be produced through: a transfer film formation step of forming a transfer surface by a phase separation by a wet spinodal decomposition; and a transfer step of using the transfer surface of the obtained transfer film as a molding die and forming a rugged pattern on a transfer target surface of an antidazzle film precursor, the rugged pattern as a reversal pattern of the transfer surface. The antidazzle film may be used as an antidazzle film of a liquid crystal display device with a touch panel or an organic EL display.SELECTED DRAWING: None 【課題】防眩性と耐擦傷性とを両立できる防眩フィルムを提供する。【解決手段】防眩フィルムに含まれる防眩層の表面形状をスキューネスＲｓｋが０未満であり、かつ粗さ曲線要素の平均長さＲＳｍが１〜５０μｍである表面形状に調整する。前記防眩層は粒径３μｍ以上の粒子を含まないのが好ましく、粒子を含まないのが特に好ましい。前記防眩フィルムのヘイズは１〜６０％であってもよい。前記防眩層表面の６０°グロスは１〜７０％であってもよい。前記防眩層は、光硬化性樹脂を含む硬化性組成物の硬化物であってもよい。この防眩フィルムは、湿式スピノーダル分解により相分離させて転写面を形成する転写用フィルム形成工程、得られた転写用フィルムの転写面を成形型とし、防眩フィルム前駆体の被転写面に、前記転写面が反転した形状である凹凸形状を形成する転写工程を経て製造してもよい。この防眩フィルムは、タッチパネル付き液晶表示装置または有機ＥＬディスプレイの防眩フィルムとして利用してもよい。【選択図】なし
