<P>PROBLEM TO BE SOLVED: To provide a low cost antireflection film in which adhesion of an antireflection layer is favorable, reflection rate is low, and reflection color unevenness is suppressed. <P>SOLUTION: An antireflection film has a thin film layer that is laminated on a polyester film whose refraction factor is 1.6 to 1.7 via only an easily adhesive layer by a gas phase film forming method. The refraction factor of the thin film layer is smaller than that of the polyester film by 0.15 or more. The easily adhesive layer satisfies the following condition 1, condition 2, or conditions 1 and 2. Condition 1: the absolute value of the difference between the refraction factor of the easily adhesive layer and that of the polyester film is 0.05 or less. Condition 2: the thickness of the easily adhesive layer is 5 nm or over and less than 50 nm. <P>COPYRIGHT: (C)2012,JPO&INPIT |
