Abstract: PROBLEM TO BE SOLVED: To realize a screen for projection which can display a picture of high contrast irrespective of outdoor daylight even if an incident angle of projection light is large and which has a wide angle of view.
SOLUTION: The screen is composed of an optical multilayered film in which high refractive index layers H and low refractive index layers L are alternatively layered. Further reflective layers 2, 3 which selectively reflect light of wavelength regions of each RGB color are superposed by holding a screen substrate 1 therebetween and a light diffusion layer 4 is arranged at one side and a light absorbing layer 6 is arranged at the other side. In this constitution, film thickness of the reflective layers 2,3 is designed so that their reflection spectra shift to each other. Thereby half-value width of RGB of reflection spectrum as the screen is widened and a margin of shift to a short wavelength side by the incident angle is widened.

Abstract: PROBLEM TO BE SOLVED: To provide a projection screen capable of providing a clear and sharp image thereon without being affected by the brightness of a projection environment.
SOLUTION: The projection screen displays an image by projecting the narrow-band primaries wavelength band light, and includes on a screen substrate 2 an optical thin film 3 having a high reflection characteristic to the narrow- band primaries wavelength band light and a high transmission characteristic to the visible wavelength band light other than the aforementioned wavelength band light. In the projection screen, the optical thin film 3 plays a role as a so-called band filter. That is, the optical thin film 3 functions as a narrow-band primaries wavelength band filter having the effect of particularly reflecting the narrow-band primaries wavelength band light and substantially transmitting the light of the other wavelength, thereby separating these two kinds of light.

Abstract: PROBLEM TO BE SOLVED: To easily and surely form an electrode such as for grounding in a functional film by subjecting a functional film consisting of a multilayered film including a conductive layer to dry etching to remove a part of the nonconductive outermost layer film so as to locally expose a desired position of the inner conductive layer. SOLUTION: A functional film consisting of a multilayered film is formed on a glass substrate 10. The multilayered film consists of first to fourth layers 11 to 14, in which the outermost layer 14 is a nonconductive antireflection layer comprising SiO2 or the like and the inner layer 13 is a conductive layer comprising ITO or the like as a shield from electromagnetic waves. An aperture 28 of a vacuum chamber 20 having an O-ring 29 around the aperture is pressed to the upper face of the functional film, and the chamber is evacuated. Then voltage is applied on an etching electrode 22 through a supporting plate 21, while an etching gas is introduced to produce plasma 33. Thereby, the outermost layer 14 is partially etched in the area corresponding to the aperture 28. The conductive layer 13 is locally exposed and a grounding electrode is surely connected to the exposed layer.
