Abstract
An object of the present invention is to provide a backlight film that uses a wavelength conversion film used for a liquid crystal display or the like, has satisfactory durability, and is able to emit light without color unevenness. The object is achieved by including a wavelength conversion film having a wavelength conversion layer and a gas barrier film that sandwich the wavelength conversion layer; and at least one reflective layer provided on one main surface of the wavelength conversion film and causing a film thickness distribution of the reflective layer to be ±5% or less.
