A display has a closed body, a display panel, an inactive propeller, an inactive magnet and a driving assembly. The closed body has an inner cavity and liquid. The display panel is mounted around by the closed body. The inactive propeller is mounted rotatably in the inner cavity and has multiple blades to agitate the liquid. The inactive magnet is mounted securely in the inactive propeller. The driving assembly is mounted on the closed body outside the inner cavity and has a power unit, a shaft and an active magnet. The active magnet is attached to the shaft and corresponds to the inactive magnet. With the magnetic force between the active and inactive magnets, the power is transmitted into the closed body without any physical contact. Therefore, the closed body does not require any waterproof structures and the liquid maintains clean and isolated from the outer environment.
