The present invention relates to an information display apparatus. According to the present invention, the information display apparatus capable of changing volume according to gas injection includes a flat information display unit, a substrate, and a gas injection port. The substrate has a three-dimensional (3D) structure in which an electrode is applied to the information display unit, and the volume is changed according to gas injection to maintain the information display unit in a flat state. The gas injection port is used to inject gas into the substrate. According to the present invention, a lower substrate having the 3D structure allowing gas injection and gas exhaustion is employed, so a flexible information display device can be maintained in a flat state when the gas is injected. In addition, as the gas is exhausted, the apparatus can be bent, rolled, and stored when being transferred. Further, gas lighter than air is injected, so the apparatus can be floated in the air. Accordingly, the power of transmitting information can be improved. In addition, a device, which can generate electric energy by itself, is attached to another surface of the substrate. Accordingly, the semi-permanent floating-type information display apparatus can be realized. |
