A projection screen comprises a red-reflecting particle layer,
green-reflecting particle layer and blue-reflecting particle layer
sequentially stacked on a substrate. In each particle layer, particles
are accumulated by eleven cycles in a regularly alignment such as close
packed structure. Diameter of red reflecting particles is approximately
280 nm, diameter of green-reflecting particles is approximately 235 nm,
and diameter of blue-reflecting particles is approximately 212 nm. Each
particles layer is accumulated by self-organized technique. The substrate
used here can absorb light of wavelengths other than those of red, green
and blue three primary colors.
