Abstract

Regardless of the physique and riding posture of the driver in a car, this invention provides an on vehicle display and light-guiding plate with superior visibility, without blocking the front view. A transparent light-guiding plate 100 which can see through the other side from the principal plane of one side, is provided in such a manner that it inclines rearwards and in front of the driver's front view, wherein the principle plane 104a of one side opposes the drivers, with an incident end at a lower end, and a reflected end 102 at a top end. A radiating body is provided at the incident end of the light-guiding plate 100. The distance from the incident end to the reflected end is long in relation to the plate thickness. The reflected end 102 of the light-guiding plate 100 may also includes plural faces with various inclining angles, or being subjected to grinding. The principle plane 104a of one side of the light-guiding plate 100 is formed with grooves 101 along directions normal to the light-guiding direction.
