<P>PROBLEM TO BE SOLVED: To provide an information display medium with metal nano particles, capable of superimposing a large amount of information. <P>SOLUTION: A unit cell 11 for absorbing visible light of a wavelength corresponding to diameters of various kinds of metal nano fine particles, and mixing a complementary color thereof, and displaying the mixed color is provided by forming two or more kinds of metal nano fine particles with different diameters. In the unit cell 11, the diameters of various kinds of metal nano particles are previously controlled according to each wavelength of visible light to be absorbed, and an area ratio of the various kinds of metal nano fine particles corresponding to a mixture ratio of a complementary color necessary for displaying a desired mixed color is previously controlled. <P>COPYRIGHT: (C)2013,JPO&INPIT |
