<P>PROBLEM TO BE SOLVED: To provide a laminated polyester film excelling in adhesion to a liquid crystal layer, stabilizing the liquid crystal layer over a long period without causing yellow discoloration, reducing interference irregularity due to external light reflection, and exhibiting excellent adhesion to various surface function layers such as a hard coat layer. <P>SOLUTION: This laminated polyester film includes a coating layer formed of a coating liquid containing a nadimide compound on one surface of a polyester film including at least three layers, containing an ultraviolet absorbing agent and having a thickness of 75-350 μm, and includes a coating layer, on the other surface of the polyester film, formed of a coating liquid containing a metal oxide and two or more types of crosslinking agents. The absolute reflectance of the surface of the latter coating layer has one minimum value in the wavelength range of 400-800 nm, and the absolute reflectance in the minimum value is ≥4.0%. In the laminated polyester film, the light transmittance at a wavelength of 370 nm of the laminated film is ≤2.0%. <P>COPYRIGHT: (C)2013,JPO&INPIT |
