A red fluorescence conversion composition includes a color conversion material (A) which absorbs light in a blue region and emits light having a fluorescence emission maximum in yellow-orange regions; a color conversion material (B) which absorbs light in the yellow-orange regions and emits light having a fluorescence emission maximum in the red region; and a matrix resin (C) for dispersing the color conversion materials (A) and (B). The color conversion material (A) is a condensed polycyclic compound made of a 5-membered ring compound having a conjugated system, and a 6-membered ring compound having a conjugated system with the 5-membered ring compound. The 5-membered ring compound contains at least one kind of atom selected from a hetero atom, a selenium atom, and a boron atom. A red fluorescence conversion film is made of the composition.
