Fluorescent screen and image display device provided with same

摘要

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.

1. A fluorescent screen comprising:
phosphor regions that contain fluorescent material that absorbs first linearly polarized light and emits fluorescent light; a diffusion region that diffuses said first linearly polarized light; and a polarizing layer that is arranged on the side of said diffusion regions into which said first linearly polarized light is entered,wherein said polarizing layer transmits said first linearly polarized light and reflects second linearly polarized light whose vibrational direction differs from that of said first linearly polarized light.
