<P>PROBLEM TO BE SOLVED: To provide an antireflection film which is free from the interference irregularity of external light reflection by improving a photopic contrast when disposed on the outermost surface on a display. <P>SOLUTION: A polyester film for an antireflection film has: a coated layer on one side of a three-layered polyester film; an average absolute reflection factor in a wave length of 400-800 nm on the coating layer surface of not less than 4.5%; a light absorbing agent in an inner layer thereof; and an average light transmittance in each wave length range of the value satisfying simultaneously following formulae (1)-(6): T<SB>440-460</SB>-T<SB>480-500</SB>≥3% (1), T<SB>440-460</SB>-T<SB>560-580</SB>≥3% (2), T<SB>520-540</SB>-T<SB>480-500</SB>≥3% (3), T<SB>520-540</SB>-T<SB>560-580</SB>≥3% (4), T<SB>610-630</SB>-T<SB>480-500</SB>≥3% (5) and T<SB>610-630</SB>-T<SB>560-580</SB>≥3% (6). <P>COPYRIGHT: (C)2008,JPO&INPIT |
