This display system includes: a projection device including a phase-modulation-type spatial light modulator element, a light source radiating light to a display part of the element, and a control circuit controlling the element and the light source; and projecting reflection light of the part of the element; and a reflecting mirror reflecting projection light of the device. The control circuit displays, on the part of the element, a first pattern and a second pattern associated with display information having different definition degrees. The reflecting mirror includes a first reflection region causing reflection light of a portion where the first pattern is displayed to enter, and reflecting the light toward a first display region, and a second reflection region causing reflection light of a portion where the second pattern is displayed to enter, and reflecting the light toward a second display region.
