A fluorescent screen includes phosphor regions 1-R, 1-G, diffusion region 1-B and reflecting means 10 formed on a region that includes phosphor regions 1-R and 1-G and diffusion region 1-B. Reflecting means 10 includes fluorescent light reflecting layer 11, phase difference layer 12, and polarizing layer 13 deposited in that order. Fluorescent light reflecting layer 11 transmits excited light 4 and reflects fluorescent light from phosphor regions 1-R and 1-G. Polarizing layer 13 both transmits excited light 4 and, of diffused light of the excited light (4) that was entered from diffusion region 1_B through Phase difference layer 12, transmits TM polarized light and reflects TE polarized light.
