A display system of one aspect according to the present disclosure includes: a display unit; a first optical member; and a second optical member. The display unit includes a display surface for displaying an image. The first optical member includes a first reflective surface for reflecting rays of light constituting the image. The second optical member includes a second reflective surface for reflecting rays of light reflected from the first reflective surface to form a virtual image in a target space. An angle of view in a length direction of an available area for display of the virtual image with regard to a point of view position for the virtual image is denoted by θ [deg]. A length of the display surface is denoted by W [mm]. W is equal to or greater than a prescribed value given by 12.0×θ−26.6. θ is equal to or greater than 8.0.
