A display system (1) includes an optical device (15) through which light diverges, a light deflector (13) configured to scan a light emitted from a light source (11) in a main scanning direction and a sub-scanning direction orthogonal to the main scanning direction to form an intermediate image (40) on the optical device (15), and an imaging optical system (30) configured to project diverging light (153, 157, 158) diverging through the optical device (15) to form an image. An effective diameter a of a mirror of the light deflector (13) for the intermediate image (40) and a ratio c of a size of an image (45) formed by the imaging optical system (30) to the effective diameter a satisfy a condition in an equation given below.
