Abstract
In an on-vehicle display device, projection light output from a projecting unit is reflected on an intermediate mirror and is further reflected on a directional mirror. The reflected light is directed to a windshield glass as directed reflected light. In an adjustment operation, the directional mirror is rotated around tilting fulcrum parts by a driving unit to adjust the height of a virtual image formed in front of the windshield glass. In a retracting operation, the lower end of the directional mirror is largely moved forward by the driving unit, rotating the directional mirror with an abutting point between the directional mirror and the upper support acting as a fulcrum. This prevents external light (sunlight) from adversely affecting the projecting unit.
