The invention relates to an anti-reflection film and an image display device. An antireflection film (101) is provided with: a hard coat film (1) provided with a hard coat layer (11) on one main surface of a transparent film substrate (10); and an antireflection layer (5) and an antifouling layer (7) provided in this order on the hard coat layer (11). The hard coat layer contains a binder resin, microparticles having an average primary particle diameter of 1-8 [mu] m, and nanoparticles having an average primary particle diameter of 100 nm or less. The anti-reflection layer is formed from a laminate of a plurality of thin films having different refractive indexes. The anti-reflection film has an average interval RSm of recesses and projections of 120 [mu] m or more as determined from a roughness curve having a measurement length of 12 mm, and an arithmetic average height Sa of 2.0 nm or more as determined from the three-dimensional surface properties of a 1 [mu] m * 1 [mu] m region. 本发明涉及防反射薄膜以及图像显示装置。防反射薄膜(10
