<P>PROBLEM TO BE SOLVED: To provide a near-infrared ray schielding component which has a near-infrared ray schielding property and a visible ray transmissivity suitable as a optical filter for a plasma display as to schielding the wave length region that can not satisfactorily be schielded by a conventional near-infrared ray absorbent material in single use. <P>SOLUTION: The method for manufacturing the near-infrared ray schielding component comprises the coating of a near-infrared ray absorbing paint consisting of an infrared ray absorbing material, a binder base material having a refractive index of 1.4 or less, and an organic solvent, on the at least one surface of an optical transmittable base material; and the near-infrared ray schielding material has on the at least one surface of an optical transmittable base material the near-infrared ray schielding layer comprising a mixture of an imonium compound and a binder having a refractive index of 1.4 or less, and has an average-transmissivity in the visible ray region of 65% or more and a transmissivity at the wave length of 850-1,000 nm of 10% or less. <P>COPYRIGHT: (C)2003,JPO |
