PROBLEM TO BE SOLVED: To provide a display device that focuses on each of a plurality of screens where an intermediate image is formed even if the display device is simply configured to enable a light beam to be made incident.SOLUTION: A display device comprises: a light source 10 that emits a light beam composed of a light component of a plurality of colors; a scanner 20 that selectively reflects the light beam from the light source 10 toward one of two screens (30a and 30b), and scans the reflected light beam over the screens (30a and 30b); a projection optical system 40 that projects an image in accordance with an intermediate image to be formed on the screens (30a and 30b) by scanning of the light beam of the scanner 20; and a lens 50 that is arranged in an optical path from the scanner 20 to the screen 30b, and focuses on the light beam from the scanner 20 in the screen 30b. In the screen 30a, the light beam from the scanner 20 is focused on without use of the lens 50.SELECTED DRAWING: Figure 1 |
