Disclosed is a phosphor-containing film capable of suppressing deterioration of the phosphor, and also suitable for production by a roll-to-roll system, and a backlight unit provided with the same. Between the two opposing base film, the 1st resin layer which has a 1st uneven shape on one main surface, and the 2nd which has the 2nd uneven shape which faces the main surface which has the 1st uneven shape of the 1st resin layer It has a 3rd layer which followed the 1st uneven shape and the 2nd uneven shape between a resin layer and a 1st resin layer and a 2nd resin layer, and the two base film is a support film and a barrier to a support film, respectively It is a barrier film in which a layer is laminated, the first resin layer and the second resin layer contain a phosphor, and the third layer is formed of an inorganic material. |
