Abstract (en)

The road display apparatus in accordance with the present invention is used such that the presence of a variety of displays such as a pedestrian crossing, a guard rail and the like is clearly recognized by vehicle drivers and pedestrians at all times day and night regardless of good or bad weather conditions. The road display apparatus comprises a display and a light emitting member ( 5) disposed at the display at a predetermined portion thereof, the light emitting member ( 5) having (i) a light absorbing surface ( 5s) for absorbing light coming from a variety of light sources such as the sun's rays, the headlights of motor vehicles, road lamps and the like, and (ii) a light radiating portion ( 5e) for emitting the light absorbed by the light absorbing surface ( 5s), as secondary light, which is then radiated to the outside. Thus, since a variety of light sources are efficiently utilized, an energy can be advantageously saved. <IMAGE>
