A display device for displaying a marking in the form of a distance to be kept between game equipment, in particular a football, and a participant on a playing field of a sports facility, includes a display device for projecting light beams representing the marking onto the playing field. The projected light beams display the distance to be kept, and can be projected at least in sections in the shape of a circle, for example at a distance of 9.15 m, around the game equipment on the playing field. The display device is jointly movable with a transport device that is movable above the sports facility.
