PROBLEM TO BE SOLVED: To provide a laminated polyester film for a liquid crystal display, which has high luminance, allows a high-quality image to be formed, and has the excellent coated external appearance even after an active energy ray-curable resin layer is formed by coating. SOLUTION: The laminated polyester film for optical use consists of at least three layers and has a coated layer on both sides thereof, which coated layer is formed in a production process thereof. The laminated polyester film for optical use is characterized in that the amount of the antimony element contained in the laminated polyester film is≤220 ppm, the transmittance of all of light beams is≥85%, the average value (Rave) of absolute reflectance of the light of 400-800 nm wavelength on the surface of one coated layer is≥4.5%, and the transmittance of the light of the following wavelength satisfies the expression:ΔT=T<SB>B</SB>-T<SB>A</SB>≥-1% (wherein T<SB>A</SB>is the average value of the transmittance of the light of 500-600 nm; and T<SB>B</SB>is the average value of the transmittance of the light of 700-800 nm).
