Abstract: PROBLEM TO BE SOLVED: To provide a low-cost antireflection films of superior antireflection performance and of mechanical strength and alkali resistance. SOLUTION: The antireflection film is obtained by stacking a hard coat layer 3, a high-refractive index layer 2 and a low-refractive index layer 1 on the surface of an organic film 4. Each of the layers 1-3 based on a synthetic resin, such as an acrylic resin. The layer 2 is provided with a high-refractive index by incorporating fine metal oxide particles having high-refractive index. The layer 1 is made porous, by incorporating fine particles 5 of a metal oxide or a fluororesin in large quantities so as to fully lower the refractive index.

Abstract: PROBLEM TO BE SOLVED: To provide a laminated film which is formed by laminating a metal oxide thin film and a metal thin film alternately in a number of layers on a base and which is useful as a transparent conductive thin film or a heat wave reflecting film disposed in front of PDP and is of low resistance and excellent in conductivity. SOLUTION: In the laminated film of the metal oxide thin film 2 and the metal thin film 3 formed on the base 1, a layer 4 of an oxide of the metal constituting the metal thin film is formed on the interface of the metal thin film 3 with the metal oxide thin film 2. In the method of forming the laminated film wherein the metal oxide thin film 2 and the metal thin film 3 are formed by laminating the base 1 with a sputtering process, the layer 4 of the oxide is formed by exposing the metal thin film 3 to an oxygen gas atmosphere after this film is formed.

Abstract: PROBLEM TO BE SOLVED: To obtain a panel laminate which may be improved in productivity and reduced in a cost and is provided with good near IR cutting performance so as to surely prevent the malfunction of a remote controller by forming near IR cut layers of a combination of plural layer of near IR cut layers. SOLUTION: The panel laminate 1 is formed by laminating and integrating conductive mesh 3 and the near IR cut films 5A and 5B by using intermediate films 4A to 4D for adhesion which are adhesives, between a transparent substrate 2 and a PDP body 20. The peripheral edges of the conductive mesh 3 protruding from the peripheral edges of the transparent substrate 2 are folded along the peripheral edges of the transparent substrate 2 and are stuck to the transparent substrate 2 by conductive tacky adhesive tapes 7. The panel laminate 1 is formed by integrating the near IR cut layers in the manner described above and, therefore, the near IR cutting property may be obtained together with electromagnetic wave shieldability, the malfunction of the remote controlled may be prevented and the radiation heat from the display section may be reduced.

Abstract: PROBLEM TO BE SOLVED: To obtain a thin film essentially consisting of silicon carbide having an optional refractive index in a specified range on a base material by executing sputtering in such a manner that silicon carbide is used as a target, and the electric power to be supplied to the target is controlled. SOLUTION: The surface of a base material is provided with a thin film in which the refractive index lies in the range of 1.8 to 2.4. Preferably, sputtering is executed in such a manner that the concn. of reactive gas is controlled as well, moreover, as a silicon carbide target, a silicon carbide sintered body having >=2.9/cm3 density and obtd. by sintering a mixture in which silicon carbide powder and a nonmetallic sintering assistant are homogeneously mixed is used. Since the SiC target material using the silicon carbide sintered body has electric conductivity, DC sputtering or DC magnetron sputtering is desirably executed. As the base material, an inorganic material such as glass, ceramics, a metallic material, an organic material such as PMMA, PET can be used. A laminated film having an optional change in the thickness direction in the range of 1.4 to 2.8 refractive index can surely be formed.
