<P>PROBLEM TO BE SOLVED: To provide a CaTiO<SB>3</SB>:Pr based fluorescent material which has a brightness higher than conventional and to provide a fluorescence display device. Ž<P>SOLUTION: A CaTiO<SB>3</SB>:Pr, Zn, Li, RE fluorescent material is a CaTiO<SB>3</SB>:Pr, Zn, Li based fluorescent material in which Pr, Zn and Li are added to CaTiO<SB>3</SB>as a first addition material and a second addition material, wherein one (RE) of Gd, La and Y is further added as a third addition material so that these Gd, La and Y enhance the brightness without preventing luminescence of other rear earth element and therefore the obtained brightness is higher than conventional.
