PROBLEM TO BE SOLVED: To provide a laminated polyester film for a liquid crystal display, having a property of enlarging a display color gamut of the liquid crystal display. SOLUTION: The laminated polyester film comprises at least three layers, wherein an inner layer contains a light absorbing agent, the average values (T<SB>535-555</SB>, T<SB>570-590</SB>, and T<SB>600-620</SB>, respectively) of light transmittance at light wavelengths of 535-555 nm, 570-590 nm, and 600-620 nm satisfy the following expressions (1) and (2) at the same time, a total light transmittance is 75% or more, both sides of the film has coating layers disposed in a manufacturing process of the film, and an average value (Rave) of absolute reflectance at light wavelengths of 400 to 800 nm on a surface of one of the coating layers is 4.5% or more. Expression: (1) (T<SB>535-555</SB>-T<SB>570-590</SB>)≥3%, Expression (2): (T<SB>600-620</SB>-T<SB>570-590</SB>)≥3%. COPYRIGHT: (C)2009,JPO&INPIT
