(Problem) It has a practically sufficient reflection performance in the visible light region, can stably form a film even when inorganic fine particles are added at a high concentration, and has an antistatic coating film to prevent adhesion of dust and dust to the surface, Antistatic white polyester film for surface light source reflecting plate which can control glossiness of front and back, and can use suitably as base material for reflecting plate for liquid crystal display and light-proof board To provide.n n n (Solution means) As a polyester film which has a base material layer which uses a polyester resin, and the antistatic coating layer whose surface specific resistance value in 23 degreeC and 50% of a relative humidity is 3 * 10 < 12> ( ohm) / square or less, It is a wavelength. For surface light source reflecting plate whose average reflectance in 400-700 nm is 90% or more with respect to one side of a polyester film, and the difference of glossiness (60 degrees) of one side and the other side of a polyester film is 5-80.
