Abstract

The present invention relates to a laminated polyester film and a mirror reflection film made of laminating the metal film layer on the surface layer (A) of the said laminated polyester film. The laminated polyester film comprises the layer structures of the surface layer (A) / whiteness light shielded layer (B), wherein the said whiteness light shielded layer (B) contains polyester composition made of that the internal comprises at least one of the empty or inorganic particles, the said surface layer (A) is a smooth layer with that the surface is form by the polyester in which the three dimension ten points average roughness (SRz) is less than 0.23μm. The light transmitting ratio of the laminated polyester is less than 20%. Obtained the high and uniform light transmitting ratio, therefore the laminated polyester film is adaptable to be a mirror refection film with high luminance, especially to be the substrate of the face light source reflection film for LCD.
