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.
