PROBLEM TO BE SOLVED: To provide a laminated polyester film for optics, hardly lowering the luminance when being used as an optical diffusion film and having excellent light diffusion ability. SOLUTION: The laminated polyester film for optics is formed of polyester composition containing pearl pigment, the average major axis of the pearl pigment is 0.5-125μm, the content of pearl pigment in the polyester composition is 10-5,000 ppm, and the total light transmittance of the film at a wavelength of 550 nm is 70% or more.
