Abstract
A head-up display system includes a display that emits a light flux visually recognized by an observer as the virtual image, and a light guide body that guides the light flux to the light-transmitting member. The light guide body includes an incident surface on which the light flux from the display is incident and an emission surface from which the light flux is emitted from the light guide body. The light flux incident on the incident surface of the light guide body is changed in a traveling direction in the light guide body, the light flux is replicated into a plurality of light fluxes in a direction perpendicular to a horizontal direction of the virtual image visually recognized by the observer to be emitted from the emission surface so as to expand a visual recognition region.
