As a film for a backlight using a wavelength conversion film used in a liquid crystal display or the like, an object of the present invention is to provide a film for a backlight that has good durability and enables light to be emitted without color unevenness in a backlight unit. The problem is solved by having a wavelength conversion film having a wavelength conversion layer and a gas barrier film sandwiching the wavelength conversion layer, and a reflection layer provided on one main surface of the wavelength conversion film, wherein the area variation of the reflection layer is ±5% or less. |
