ABSTRACT:
A transmissive screen includes, sequentially from a projection side, a Fresnel lens having a condensing function, a diffusion plate for diffusing incident light, and a front-surface protective panel disposed facing the diffusion plate across an air flow layer of a predetermined interval. The front-surface protective panel partially absorbs visible light, and the visible light absorbance of the front-surface protective panel is made the highest compared with the Fresnel lens and the diffusion plate.
