摘要： PROBLEM TO BE SOLVED: To make a filter have absorption in a near-infrared ray region, to improve the light transmissivity in a visible region and to prevent the filter from having the large absorption of a specified wavelength in the visible region by making the transmissivity in the near infrared ray region of a specified wavelength range less than a specified value. SOLUTION: For this infrared-ray absorption filter, the transmissivity in a near infrared-ray region of a wavelength 800 nm-1,100 nm is less than 30%. Since the transmissivity in this area is low, in the case of using it in a plasma display or the like, unrequired infrared rays emitted from the display are absorbed and the malfunction of a remote controller using the infrared rays is prevented. Also, it is desirable that the difference of the maximum value and minimum value of the transmissivity in the visible region of the wavelength 450 nm-650 nm be within 10%. When the transmissivity difference of the wavelength 450 nm-650 nm is within the range, the color tone becomes gray and in the case of placing it on the display front surface, the color tone emitted from the display is expressed without being changed. Further, it is preferable that the transmissivity of the wavelength 550 nm is more than 50%.

摘要： PROBLEM TO BE SOLVED: To establish both high electromagnetic shielding property and high total ray transmittance by allowing at least the single-surface shape of a transparent macromolecular film to be in a sawtooth shape and coating only one surface out of two surface of a triangular column with metal with improved conductivity. SOLUTION: A transparent polyester film is coated with an acryl UV-curing resin and irradiated with UV rays until a gel shape is attained, a roller is pressed for shaping into a triangular shape, and furthermore it is irradiated with UV rays for complete curing. In this case, an angle formed by a surface where a conductive surface 2 in the two surfaces of the triangular column 1 is not formed and a transparent macromolecular film 3 is preferably equal to 30 degrees or less. Then, the manufactured film is loaded into a vacuum deposition device and is set to that the angle formed by a deposition source and a film normal line is 45-90 degrees, thus depositing aluminum and hence improving total ray transmittance and electromagnetic wave shielding property.
