A display system is provided with a display device; the display device including: a light source configured to emit light; and a light guide element configured to guide incident light from the light source; the light guide element including: an emission surface configured to output incident light; and a plurality of light focusing portions configured to change the path of the incident light toward the emission surface, causing the light output to converge toward a convergence point or convergence line outside the light guide element or to radiate from a convergence point or convergence line outside the light guide element and thereby form an image outside the light guide element. The display device presents information as an image, e.g., as a stereoscopic image.
