<p>A projection display D comprises an acquisition means (2) for acquiring the pixel value Cg and the depth value Cz of each pixel constituting an image, a light emitting means (3) for outputting a pixel display light Ld corresponding to the pixel value for each pixel, an optical conductor (5) for introducing the pixel display light Ld to the position on a projection screen (8) corresponding to the pixel, and a control means for varying the optical path length of the pixel display light Ld to the projection screen (8) depending on the depth value Cz of the pixel. The optical conductor (5) is provided with a reflector (51) having mirror surfaces (511a) facing each other. The optical path length control means (3) varies the number of reflecting times of the pixel display light on the mirror surfaces (511a) of the reflector (51) depending on the depth value Cz of the pixel.</p> |
