PROBLEM TO BE SOLVED: To provide an evaluation method and an evaluation device capable of evaluating gas permeability of a thin film simply, accurately at low cost. SOLUTION: A substrate 11 for evaluation composed by forming a conductive detection layer 13 on a substrate 12 is prepared, and the thin film 14 which is an evaluation object is installed on the detection layer 13, and a carrier density or resistivity which is an electric characteristic of the detection layer 13 is measured. A phenomenon that the carrier number of the detection layer 13 which is a lower layer is changed by an influence of gas or liquid permeating the thin film 14 is detected as the electric characteristic of the detection layer 13, to thereby quantitate and evaluate indirectly the permeability of the thin film 14 relative to the gas or the liquid.

Abstract:
PURPOSE:To provide a vacuum deposition device which enhances productivity and can reduce the cost of materials because vacuum deposition on parts not requiring vacuum deposition such as the inner wall of the vacuum vessel can be avoided. CONSTITUTION:A crucible 1 contg. an evaporating material 2 as an evaporating source is heated with a high-frequency induction heating source 3 to evaporate the evaporating material 2 and the resulting vapor is deposited in vacuum on a body 4 to be vacuum-deposited. At this time, a shielding cover 5 and a cooling nozzle 6 are interposed between the body 4 and the crucible 1 so that vapor of the evaporating material 2 scattered only in the perpendicular direction is fed from the opening in the nozzle 6 and deposited on the body 4 to be deposited in the form of a flow of vapor. The remaining component other than the component depositing on the body 4 is stuck and deposited on the opening 6a.

Abstract:
PROBLEM TO BE SOLVED: To provide a screen for projection that can obtain a clear image without being influenced by a projection environment, and to provide its manufacturing method. SOLUTION: An anti-reflection layer 14 is provided on an optical diffusion layer 13 of the surface of the screen. The anti-reflection layer 14 includes a wavelength of laser light of each color emitted as projection light from a light source of a projector. Light of a wavelength region within a range of 450 nm or more and 650 nm or less has low reflection characteristics in which a reflectance is 0.5 % or less. Even when excessive light except for projection on the surface of the screen enters, contrast of an image is enhanced since reflection is suppressed with the anti-reflection layer 14.
