There is provided a display apparatus by which different information and images can be seen depending on a view angle and a viewer, a stereoscopic image can be seen realistically from surrounding directions, and a binocular stereoscopic vision is realized without using glasses and the like. The display apparatus according to the invention is characterized by including a rotary mechanism which rotates a polygonal pyramid body having a mirror on its surface and a disk having a slits fixed coaxially with the polygonal pyramid body, a display part which thereby displays images for projecting information or images differing from each other in accordance with an angle direction in which each side surface of the polygonal pyramid faces on each side surface of the polygonal pyramid body, and a light source part for projecting the images displayed on the display part onto the polygonal pyramid body.
