Abstract
Provided is a projection apparatus for projecting an image which can be seen stereoscopically, wherein the apparatus is made smaller and the definition of the projected image is higher than would be the case if the present configuration were not employed. The projection apparatus is an apparatus for projecting an image which can be seen stereoscopically, by scanning with one set of at least red, green, and blue laser beams, and includes a light source section that emits the laser beams, a scan section that scans a projection region two-dimensionally with the laser beams, and a microlens array that includes microlenses on which the laser beams from the scan section are incident and that changes emission angles of the laser beams in accordance with incident positions of the laser beams on the microlenses to create a light ray field in which light rays whose positions and directions are controlled are emitted from each point on surfaces of the microlenses in accordance with an image to be projected.
