The display apparatus has an endless drive member (15) wound on drive sprockets and driven sprockets so that the drive member travels along a circulating travel path. An array of display plates (18) are attached to a specified region of the endless drive member (15) in such a manner that each of the display plates (18) can be swiveled. First, when the display plates are lined at the front part of the path, an advertising sign on their front surfaces is shown. As the display plates move, driven by the drive member, and pass the left end of the circulating path, they are guided by a first guide member (25,26) in such a way that they maintain the same attitude. When they enter the rear part of the circulating path, an advertising sign on a stationary display board (28) installed inside the endless drive member (15) can be seen unobstructed. As the drive member is driven again to move the display plates (18) past the right end of the circulating path, the display plates are guided by a second guide member (27) to swivel a half turn, showing their back. When the display plates are lined at the front part of the path again, the advertizing sign on their back is shown. In this way, three different advertising signs can be seen unobstructed one after another during one complete turn of the endless drive member. <IMAGE>
