Claims

[Scope of claim for utility model registration] A display light emitting part that projects driving information toward a display part provided inside the front wind panel;
In a vehicle display device in which a transparent body is interposed in the optical path of display light emitted from the display light emitting section, an incident surface and an output surface of the display light of the transparent body,
A display device for a vehicle, characterized in that the display device is configured as a miscellaneous light removing surface that emits internally reflected light that is internally reflected within a transparent body and emitted from an output surface out of a driver's visual recognition area.
