Abstract
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.
