PROBLEM TO BE SOLVED: To provide a polyester film excellent in adhesiveness when it is used as a polyester film for a hard coat, having high transparency without particle feeling, high brightness, scratch resistance with few scratches, little uneven interference with the hard coat, and provide. SOLUTION: At least a multilayer polyester film containing 0.05% by weight or more of inorganic particles each having a primary particle size of 1.0 μm or less and a Mohs hardness of 7 or more in both outermost layers composed of a polyester layer having a thickness of 1.5 μm or more. It has a hard coat layer on one side, the image transmittance at an optical comb width of 0.125 mm is 94% or more, and in the wavy chart for measuring the absolute reflectivity of the hard coat layer surface, the reflectivity between adjacent peaks and valleys A multilayer polyester film having a minimum difference in a wavelength range of 500 to 650 nm.
