The present invention is a flame-retardant polyester film including resin layers laminated on both surfaces of a polyester film, wherein the resin layer satisfies 15&#x2266;(Wc&#x2212;Wc)/Wc&#xd7;100&#x2266;99 (where Wcrepresents the weight of the resin layer, Wcrepresents the weight of the resin layer after the temperature thereof is raised from 25&#xb0; C. to 600&#xb0; C. in air, and Wcrepresents the weight of the resin layer after the temperature thereof is raised from 25&#xb0; C. to 800&#xb0; C. in air), and has a non-flammable gas generating rate of 3 to 40 percent over the range of 180&#xb0; C. to 450&#xb0; C. The present invention provides a flame-retardant polyester film having an excellent flame retardancy, and adhesive tapes, flexible printed circuits, a membrane switch, a film heater, and a flat cable, each including the flame-retardant polyester film.

A hardcoat film comprises a substrate film, and a hardcoat layer laminated on at least one side of the substrate film, wherein a reflectance of the hardcoat layer at a wavelength within 400 to 600 nm has a mean ripple amplitude of 1% or less. The hardcoat film has decreased iris patterns. There is also provided an antireflection film having a low surface reflectance and a neutral tone of color, and an equipment for display including the film.
