PROBLEM TO BE SOLVED: To provide an image displaying medium, which can be manufactured at a low cost, has a high designedness, necessitates no use of discriminating apparatuses, can prevent a falsification with a copier, a scanner or the like from developing and can display even variable information at low cost, and its manufacturing method. SOLUTION: By printing a first straight line group 1L1 and a second straight line group 1L2, each of which is a parallel line-like straight line assemblage and which are shifted by nearly a half pitch to each other, on a displaying surface having a parallel-line like unevenness thereon, 'ABC' in white characters on a black ground is made to be observed when the medium is seen from a direction indicated with an arrow A, while 'ABC' in black characters on a white ground is made to be observed when the medium is seen from a direction indicated with an arrow B. |
