An image display medium (1) has a structure, where a film body (2) having a number of fine film pieces (2a) provided corresponding to display pixels is held between a supporting member (3) and a covering member (4). The supporting member (3) is provided a number of movable spaces (5) provided to individually move the fine film pieces (2a) of the film body (2). Further, on the film body (2), selective switching is made between a state where each fine film piece (2a) is adsorbed and held on the covering member (4) to shut out a light, and a state where each fine film piece (2a) is adsorbed and held on a spacing wall (5a) of the supporting member (3) to transmit a light, so that an image is displayed.
