PROBLEM TO BE SOLVED: To provide a release film which can be used for various kinds of uses of protecting a liquid crystal display panel such as a polarizing plate, a phase difference plate, ceramic releasing, etc., and which has very small quantities of oligomer deposition, and good transparency and workability. SOLUTION: The laminated polyester film for releasing is made of three or more layers of the laminated polyester films in which a double refractive index in the film is 0.020 or less, and a low molecular weight extraction amount extracted from the film surface with a chloroform is less than 15 mg/m<SP>2</SP>.
