摘要： 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.

摘要： Such a structure is to be provided in that in the case where a material, such as a protective film, is coated on a fine particle accumulated layer, such as a photonic crystal, penetration of the material into gaps among the fine particles is suppressed, whereby the mechanical strength against bending stress and tensile stress is improved, and peeling and breakage of the fine particle accumulated layer are suppressed, without adverse affect on the optical characteristics, such as reflection characteristics. The fine particle structure contains a visible light absorbing material absorbing visible light as a substrate, having accumulated thereon in this order silica fine particles having a particle diameter of 290 nm as a fine particle layer for reflecting red light, silica fine particles having a particle diameter of 240 nm as a fine particle layer for reflecting green light, and silica fine particles having a particle diameter of 210 nm as a fine particle layer for reflecting blue light, and further provided thereon a polymer layer or a gelatin layer containing a polymer having a size larger than the gaps among the fine particles. The optical medium, such as a reflective type screen, further contains a diffusion film on the polymer layer or the gelatin layer.

摘要： The present invention provides an optical switch for making part of incident light, which has been made incident on an optical waveguide, selectively emergent to a light emergence portion provided outside the optical waveguide. The optical switch includes a liquid crystal device for selective emergence of the incident light. An arbitrary layer of the liquid crystal device is set such that letting Δn be a difference between a refractive index no of the optical waveguide and a refractive index n1 of the arbitrary layer of the liquid crystal device, “d” be a thickness of the arbitrary layer, and λ be a wavelength of the incident light, the values of Δn, “d”, and λ satisfy a condition of 2.20×10−3≦|Δn·d·λ−1|≦3.03×10−3. With this optical switch, the uniformity of a light emergence efficiency can be easily realized by making use of a small change region in which the light emergence efficiency is not largely varied. The present invention also provides a display unit using the optical switches.
