<P>PROBLEM TO BE SOLVED: To provide an antireflection film which hardly causes the degradation of contrast according to a change of viewing angle, reversal of gradation or black and white, hue change and the like and has improved color irregularity and improved scratch resistance, and to provide a manufacturing method of the antireflection film. <P>SOLUTION: The antireflection film has a light-diffusing layer and a low refractive index layer on a transparent support, wherein the light-diffusing layer has an inner haze value of 30 to 60% and a surface haze value of 1% or less, and the antireflection film has an average reflectance of 2.5% or less at a wavelength of 450 nm to 650 nm. In the manufacturing method of the antireflection film, a coating device is used, wherein a top end lip 17 on the opposite side to the traveling direction of a web W and the web W are disposed so that a clearance between both becomes larger by ≥30μm and ≤120μm than the clearance between the top end lip 17 when a slot die 13 having a land 18 length of ≥30μm and ≤100μm in the traveling direction of web W of the top end lip 17 in the web W traveling direction side of the slot die 13 is set on the coating position. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
