PROBLEM TO BE SOLVED: To float a surface image in the space by laminating display sheets on both faces of a light guide plate, forming the light guide plate with a transparent layer and a light diffusing layer, and gradually increasing the thickness of the light diffusing layer toward the far side from a light source. SOLUTION: In this double-faced indicator body, the light emitted from a light source 11 is guided into a light guide plate 13a, and it passes through display sheets 14a1, 14a2 on both sides via an inclination type light scattering layer and is radiated to the outside. Pictures drawn on the display sheets 14a1, 14a2 can be observed from both side faces. The display sheets 14a1, 14a2 constituting the double-faced indicator body are made of a lightweight acrylic resin excellent in transparency, and the sheets 14a, 14a2 are preferably printed for use. |
