Optical element, display system, and mobile object

Abstract

A display system includes an optical element through which light diverges and an imaging optical system configured to form an image by projecting diverging light diverging through the optical element. In the display system, the image formed by the imaging optical system is visually recognized by a viewer, and a condition in an equation tan 0≥(T×B)/(S×O) is satisfied, where θ denotes a divergence angle of the optical element, T denotes distance between the image forming optical system and the formed image, B denotes a range of an eye box that is an area through which the formed image can visually be recognized, S denotes distance between the formed image and a viewpoint of the viewer of the formed image, and O denotes distance between the optical element and the image forming optical system. In the above equation, each distance indicates length of an optical path that passes through a center of an image formed by the light when an object is observed from a reference eyepoint.
