Title: HEAD-UP DISPLAY DEVICE
Abstract:
This head-up display device projects display light, reflected from a concave imaging reflective surface (42) disposed above an upper surface (2a) of an instrument panel (2), onto a combiner (40) having the imaging reflective surface in order to display a virtual image (VI) that can be viewed by an occupant. A projector (10) projects the display light as a beam. A light guide mirror (30) has a light guide reflective surface (32) that reflects the display light from the projector toward the imaging reflective surface. The light guide reflective surface has a convex surface shape.
