PROBLEM TO BE SOLVED: To provide a fluorescent screen which has high luminous efficiency while using an inexpensive fluophor with a large particle diameter.SOLUTION: A fluorescent screen 1 includes fluophor layers 2-4, a fine particle layer 5, a black stripe 6, a base material 7, an adhesion layer 8, and a cover material 9. Each of fine particles dispersed in the fine particle layer 5 has a particle diameter which generates Rayleigh scattering with respect to excitation light, and each of fluophor particles dispersed in the fluophor layers 2-4 has a particle diameter which generates Mie scattering or geometrical optical scattering with respect to excitation light. |
