<p>PROBLEM TO BE SOLVED: To provide a laminate polyester film suitable for protecting a polarizing plate, which can decrease degradation of a liquid crystal by UV rays when the film is assembled as a polarizing plate in a liquid crystal display and which can decrease bleed out during and after film formation.SOLUTION: The laminate polyester film comprises at least three layers, in which an inner layer contains at least two types of UV absorbents, and a content ratio of a UV absorbent with the largest content to other UV absorbent ranges from 1.1:1 to 10:1. The film has a content of UV absorbents of 0.5 to 3.0 wt.% and a transmittance for rays of 10% or more at a wavelength of 380 nm and 80% or more at a wavelength of 400 nm.</p> |
