Abstract
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.
