<P>PROBLEM TO BE SOLVED: To provide a display member having a security property. <P>SOLUTION: The display member includes: a display layer which exhibits a structural color and contains therein spherical bodies and a matrix; and a reflective interface which reflects a light transmitted through the display layer. The reflective interface is formed of the display layer and a reflective interface-forming layer which is provided in contact with the display layer. When a refractive index of the spherical bodies is na, a refractive index of the matrix is nb, and a refractive index of the reflective interface-forming layer is nc, the following formulas (1) and (2) are satisfied: (1) 0.35<nc/na<1.00; and (2) 0.35<nc/nb<1.00. <P>COPYRIGHT: (C)2010,JPO&INPIT |
